[PATCH 12/12] drm/amd/display: obtain usHBR3En bit from BP 1

[harry.wentland@xxxxxxx (Harry Wentland)]

From: Ding Wang <Ding.Wang@xxxxxxx>

ASICs using bios parser 1 don't check HBR3 capability as there is no such
a bit usHBR3En in ATOM_ENCODER_CAP_RECORDER.
Therefore, will use ATOM_ENCODER_CAP_RECORDER_V2 and thus obtain the usHBR3En
bit.
