drm/i915: Reject BIOS FB rotation in common code
Reject 90/270 degree rotated BIOS framebuffers in common
code. Currently skl_get_initial_plane_config() already rejects
these, but we may want to implement the missing parts there
so that skl_get_initial_plane_config() could be reused for
general plane state verification purposes.
90/270 degree rotated framebuffers require two completely
separate GGTT mappings (0 degree for the CPU, 270 degree
for the display engine), and the rest of the BIOS FB
takeover code is not prepared for that.
