drm/amd/display: Re-implementing ARGB16161616 pixel format as 22
[Why]
ABGR16161616 colour format was added to dcn10/20/30, and set
any ARGB16161616 to the same value as it (26). As such, the
HDR10 Green Point y value was too far off of the EDID stated
value for DisplayPort.
[How]
Added back the pixel format as 22 for ARGB16161616 for
dcn10/20/30.
