drm/amd/display: Parse scanline registers
They could differ between ASIC generations
Change-Id: Ia352ae206273fe3a025579554cae4e3711a26fcc
on agd5f drm staging 4.9/11 there is a regression with full screen video.
mpv --vo=vaapi/vdpau/opengl all the same, dropping frames, or playing slowmo
with --framedrop=no
Windowed playback is OK, testing with 60fps vid on 60Hz DVI-D display.
Forcing clocks high does not help.</pre>
