Include PCI_ERROR_RESPONSE along with 0xFFFF and 0xFFFFFFFF in the comment
about identifying config read errors. This makes checks for config read
errors easier to find. Comment change only.

Turns out the DSB has trouble correctly loading the gamma LUT.
From a cursory look maybe like some entries do not load
properly, or they get loaded with some gibberish. Unfortunately
our current kms_color/etc. tests do not seem to catch this.
I had a brief look at the generated DSB batch and it looked
correct. Tried a few quick tricks like writing the index
register twice/etc. but didn't see any improvement.
Also tried switching to the 10bit gamma mode in case
there is yet another issue with the multi-segment mode, but
even the 10bit mode was showing issues.
Switching to mmio fixes all of it. I suppose one theory is that
maybe the DSB bangs on the LUT too quickly and it can't keep up
and instead some data either gets dropped or corrupted. To confirm
that someone should try to slow down the DSB's progress a bit.
Another thought was that maybe the LUT has crappy dual porting
and you get contention if you try to load it during active
scanout. But why then would the mmio path work, unless it's
just sufficiently slow?
Whatever the case, this is currently busted so let's disable
it until we get to the root of the problem.

All interpolated gamma modes including the icl+ multi segment
mode require non-decreasing entries for the interpolation to
work correctly. For some reason we're forgetting to declare
that for icl+. Let us do so.

Let's adjust the vblank evasion to account for the case where
a push has already been sent. In that case the vblank exit will start
at vmin vblank start (as opposed to vmax vblank start when no push
has been sent).
This should minimize the effects of the tiny race between sampling
the frame counter vs. intel_vrr_send_push() during the previous frame.
This will also be required if we want to do mailbox style updates with
vrr since then we'd definitely do multiple commits per frame. Currently
mailbox updates are only used by the legacy cursor, but we don't do
vrr push for those.

When config pci_ops.read() can detect failed PCI transactions, the data
returned to the CPU is PCI_ERROR_RESPONSE (~0 or 0xffffffff).
Obviously a successful PCI config read may *also* return that data if a
config register happens to contain ~0, so it doesn't definitively indicate
an error unless we know the register cannot contain ~0.
Use PCI_POSSIBLE_ERROR() to check the response we get when we read data
from hardware. This unifies PCI error response checking and makes error
checks consistent and easier to find.

Moving the vrr push to happen before sampling the frame counter
was wrong. If we are already in vblank when the push is sent
the vblank exit will start immediately which causes the sampled
frame counter to correspond to the next frame instead of the current
frame.
So put things back into the original order (except we should
keep the vrr push within the irq disable section to avoid
pointless irq related delays here).
We'll just have to accept the tiny race that exists between
sampling the frame counter vs. vrr push. And let's at least
document said race properly in a comment.
I suppose we could try to minimize the race by sampling the frame
counter just before sending the push, but that would require
changing drm_crtc_arm_vblank_event() to accept a caller provided
vblank counter value, so leave it be for now. Another thing we
could do is change the vblank evasion to account for the case
where a push was already sent. That would anyway be required
for mailbox style updates. Currently mailbox updates are only
used by the legacy cursor, but we don't do a vrr push for those.

A config read from a PCI device that doesn't exist or doesn't respond
causes a PCI error. There's no real data to return to satisfy the CPU read,
so most hardware fabricates ~0 data.
Use PCI_SET_ERROR_RESPONSE() to set the error response when we think the
device has already been disconnected.
This helps unify PCI error response checking and make error checks
consistent and easier to find.

When a PCI config read fails, most PCI host bridges fabricate ~0 data to
complete the CPU read. But some host bridges do not; their drivers may
only return an error from the pci_ops.read() method.
In PCI_OP_READ() and PCI_USER_READ_CONFIG(), use PCI_SET_ERROR_RESPONSE()
to set the data value to indicate an error when pci_ops.read() fails.
This means the host bridge driver no longer needs to fabricate error data
when they detect errors.
This makes error response fabrication consistent and helps in removal of a
lot of repeated code.

It's fine to call dev_err_probe() in ->probe() when error code is known.
Convert the driver to use dev_err_probe().

Use the devm_platform_get_and_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately.

In the struct supplier_bindings the member 'node_not_dev' is described as
"The consumer node containing the property is never a device.", but that is
inconsistent with the behaviour of the code in of_link_property(), as it
calls of_get_compat_node() that starts parsing for a compatible property
from the node it gets passed to it. The proper behaviour is to start at the
node's parent, so let's do that.
While at it, let's take the opportunity to update the description of the
'node_not_dev' flag, as to clarify its purpose.

"ret" variable is already declared in qspi_transfer_in() at the
