Current mode validation impedes setting up some video modes which should
be supported otherwise. Namely 1920x1200@60Hz.
Fix this by lowering the minimum HDMI state machine clock to pixel clock
ratio allowed.
Fixes: 32e823c63e90 ("drm/vc4: Reject HDMI modes with too high of clocks.")

The vboxvideo driver is missing a call to remove conflicting framebuffers.
Surprisingly, when using legacy BIOS booting this does not really cause
any issues. But when using UEFI to boot the VM then plymouth will draw
on both the efifb /dev/fb0 and /dev/drm/card0 (which has registered
/dev/fb1 as fbdev emulation).
VirtualBox will actual display the output of both devices (I guess it is
showing whatever was drawn last), this causes weird artifacts because of
pitch issues in the efifb when the VM window is not sized at 1024x768
(the window will resize to its last size once the vboxvideo driver loads,
changing the pitch).
Adding the missing drm_fb_helper_remove_conflicting_pci_framebuffers()
call fixes this.
Changes in v2:
-Make the drm_fb_helper_remove_conflicting_pci_framebuffers() call one of
the first things we do in our probe() method

The "data-mapping" property may not be the best way to describe the
interface between panels and display interfaces.
Drop use of in the panel-simple driver, so we have time to find
the right way to describe this interface.

data-mapping may not be the best way to describe the
data format used between panels and display interface.
Drop it from the panel-dpi binding so we do not start to rely on it.
We can then work out how to best describe this mapping and when
we know it, we can add it to this binding.

Variables declared in a switch statement before any case statements
cannot be automatically initialized with compiler instrumentation (as
they are not part of any execution flow). With GCC's proposed automatic
stack variable initialization feature, this triggers a warning (and they
don't get initialized). Clang's automatic stack variable initialization
(via CONFIG_INIT_STACK_ALL=y) doesn't throw a warning, but it also
doesn't initialize such variables[1]. Note that these warnings (or silent
skipping) happen before the dead-store elimination optimization phase,
so even when the automatic initializations are later elided in favor of
direct initializations, the warnings remain.
To avoid these problems, lift such variables up into the next code
block.
