The current drm_atomic_helper_commit_tail helper works only if the CRTC is
accessible, and documents an alternative implementation that is supposed to
be used if that happens.
That implementation is then duplicated by some drivers. Instead of
documenting it, let's implement an helper that all the relevant users can
use directly.

rockchip_drm_framebuffer_init is only used in one case, in
rockchip_drm_fbdev.c, where its return value is tested using IS_ERR. To
enable propagating the reason for the error, change the definition so that
it returns an ERR_PTR value.
Problem found with the help of Coccinelle.

Currently the driver uses a custom function to wait for flip to complete
after an atomic commit. It was needed before because of two problems:
- there is no hardware vblank counter, so the original helper would
have a race condition with the vblank interrupt,
- the driver didn't support unreferencing cursor framebuffers
asynchronously to the commit, which was what the helper expected.
Since both problems have been solved by previous patches, we can now
make the driver use the generic helper and remove custom waiting code.

Instead of keying off vblank for psr, just flush every time
we get an atomic update. This ensures that cursor updates
will properly disable psr (without turning vblank on/off),
and unifies the paths between fb_dirty and atomic psr
enable/disable.

Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter
of the helper drm_atomic_helper_commit_planes() if the relevant display
controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes
when the CRTC is disabled. The helper would skip the ->atomic_disable
call for a plane if the CRTC of the old plane state needs a modesetting
operation. Of course, the drivers need to disable the planes in their CRTC
disable callbacks since no one else would do that.

The PSR driver have exported four symbols for specific device driver, and
it's safe to call them in interrupt context:
- rockchip_drm_psr_register()
- rockchip_drm_psr_unregister()
- rockchip_drm_psr_enable()
- rockchip_drm_psr_disable()
- rockchip_drm_psr_flush()
Encoder driver should call the register/unregister interfaces to hook
itself into common PSR driver, encoder have implement the 'psr_set'
callback which use the set PSR state in hardware side.
Crtc driver would call the enable/disable interfaces when vblank is
enable/disable, after that the common PSR driver would call the encoder
registered callback to set the PSR state.
Fb driver would call the flush interface in 'fb->dirty' callback, this
helper function would force all PSR enabled encoders to exit from PSR
for 3 seconds.

With the various bits fixed rockchip now has an atomic compliant
handling/signalling of crtc_state->event, which means we can just
switch over to the new nonblocking helpers and remove some code.
v2: Fixes from Tomeu.
v3: Send out vblank events correctly when shutting down a crtc for
good. This is part of the atomic interface contract.
v4: Properly protect vop->event.
v5: Add more WARN_ON to check vop->event isn't clobbered.

As commented in drm_atomic_helper_wait_for_vblanks(), userspace relies
on cursor ioctls being unsynced. Converting the rockchip driver to
atomic has significantly impacted cursor performance by making every
cursor update wait for vblank.
By skipping the vblank sync when the framebuffer has not changed (as is
done in drm_atomic_helper_wait_for_vblanks()) we can avoid this for the
common case of moving the cursor and only need to delay the cursor ioctl
when the cursor icon changes.
We cannot add the check on legacy_cursor_update since that results in
the cursor bo being unreferenced while the hardware may still be reading
it. Fully supporting unsynced cursor updates is left for the future
when the atomic helper framework supports async updates.
