drm/modes: Make sure to parse valid rotation value from cmdline
A rotation value should have exactly one rotation angle.
At the moment there is no validation for this when parsing video=
parameters from the command line. This causes problems later on
when we try to combine the command line rotation with the panel
orientation.
To make sure that we generate a valid rotation value:
- Set DRM_MODE_ROTATE_0 by default (if no rotate= option is set)
- Validate that there is exactly one rotation angle set
(i.e. specifying the rotate= option multiple times is invalid)
