Hans de Goede 4e7a4a6fbd drm/modes: parse_cmdline: Add support for specifying panel_orientation (v2)
Sometimes we want to override a connector's panel_orientation from the
kernel commandline. Either for testing and for special cases, e.g. a kiosk
like setup which uses a TV mounted in portrait mode.

Users can already specify a "rotate" option through a video= kernel cmdline
option. But that only supports 0/180 degrees (see drm_client_modeset TODO)
and only works for in kernel modeset clients, not for userspace kms users.

The "panel-orientation" connector property OTOH does support 90/270 degrees
as it leaves dealing with the rotation up to userspace and this does work
for userspace kms clients (at least those which support this property).

Changes in v2:
-Add missing ':' after @panel_orientation (reported by kbuild test robot)
