Add backlight driver for the panels supporting backlight control
using DPCD registers on the DisplayPort aux channel.
Changes in v2:
- New (most of the code reused from drm_dp_aux_backlight.c of v1)
Changes in v3:
- Add missing ';' to fix module compilation (kernel test bot)

The backlight level of an eDP panel can be controlled through the AUX
channel using DPCD registers of the panel.
The capability for the Source device to adjust backlight characteristics
within the panel, using the Sink device DPCD registers is indicated by
the TCON_BACKLIGHT_ADJUSTMENT_CAPABLE bit

drm_dev_register() sets connector->registration_state to
DRM_CONNECTOR_REGISTERED and dev->registered to true. If
drm_connector_set_panel_orientation() is first called after
drm_dev_register(), it will fail several checks and results in following
warning.
Create panel orientation property in drm_c

Instead of always getting the disp_state from drm device, pass it as an
argument.

Instead of allocating snapshotting structure at the driver probe time
and later handling concurrent access, actual state, etc, make
msm_disp_state transient struct. Allocate one when snapshotting happens
and free it after coredump data is read by userspace.

Maybe we should mention "multiple overlay planes" as a good task?
