drm/amd/display: Disable unbounded request mode during rotation

Browse source

[why]
HUBP_UNBOUNDED_REQ_MODE being enabled while the display is rotated (eg.
going from Portrait mode to Landscape mode) appears to be causing a
p-state hang, specifically during full screen mode on the Tiktok PC app.
Unbounded request mode doesn't appear to be supported with rotation
configs, hence disabling it.

[how]
Within DML, modified unbounded request mode to be configured only when
the rotation angle of the plane is 0.
