drm/imx: parallel-display: drop edid override support
...
None of the in-kernel DT files ever used edid override with the
fsl-imx-drm driver. In case the EDID needs to be specified manually, DRM
core allows one to either override it via the debugfs or to load it via
request_firmware by using DRM_LOAD_EDID_FIRMWARE. In all other cases
EDID and/or modes are to be provided as a part of the panel driver.
Drop support for the edid property.

drm/imx/ipuv3: do not return negative values from .get_modes()
...
The .get_modes() hooks aren't supposed to return negative error
codes. Return 0 for no modes, whatever the reason.

drm/imx/ipuv3: Convert to platform remove callback returning void
...
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert the ipuv3 imx drivers from always returning zero in
the remove callback to the void returning variant.

drm/imx: move IPUv3 driver into separate subdirectory
...
The IPUv3 and DCSS driver are two totally separate DRM drivers. Having
one of them live in the drivers/gpu/drm/imx toplevel directory and the
other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver
into its own subdirectory to make the separation more clear.
