Now that we have a callback to check if bridge supports a given mode
we can use it in Synopsys Designware HDMI bridge so that we restrict
the number of probbed modes to the ones we can actually display.

Also, there is no need to use mode_fixup() callback as mode_valid()
will handle the mode validation.

NOTE: I also had to change the pdata declaration of mode_valid
custom callback so that the passed modes are const. I also changed
in the platforms I found. Not even compiled it though.

IRQs are properly shut down, so it almost works as race-free shutdown.
Except the irq is stopped after the vblank stuff, so boom anyway.
Proper way would be to call drm_atomic_helper_shutdown before any of
the kms things gets stopped. So no harm in removing the
drm_vblank_cleanup here really.

Same story for both hdlcd and mali.

The driver is written in a way to enable compile-testing without CONFIG_ARM_AMBA,
but it just causes needless warnings:

drivers/gpu/drm/pl111/pl111_drv.c:149:26: error: 'pl111_drm_driver' defined but not used [-Werror=unused-variable]

This unhides the probe/remove functions again and just leaves the driver
object as unused when CONFIG_ARM_AMBA is disabled, with a __maybe_unused

CRTC don't seem to get shut down in a controlled fashion, but no one
bothers to stop interrupts either so this races no matter what. Might
as well remove it. A call to drm_atomic_helper_shutdown would be

This changes the connector probe helper function to use the new
encoder->mode_valid(), bridge->mode_valid() and crtc->mode_valid()
helper callbacks to validate the modes.

The new callbacks are optional so the behaviour remains the same
if they are not implemented. If they are, then the code loops
through all the connector's encodersXbridgesXcrtcs and calls the
callback.

If at least a valid encoderXbridgeXcrtc combination is found which
accepts the mode then the function returns MODE_OK.

Ideally the DRM_ROTATE_ and DRM_REFLECT_ property ids are looked up
