[PATCH v2 04/12] drm/imx: parallel-display: drop edid override support

[Dmitry Baryshkov]

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.
