[PATCH 21/34] drm/amd/display: Extend DMUB wait for DIG PHY programming commands

From: Wayne Lin <[email protected]>

[Why]
DIG transmitter ENABLE and voltage/pre-emphasis VBIOS commands can
take longer than the default inbox timeout after amdgpu reload, while
DMCUB runs extended DPPHY polling before advancing INBOX1 RPTR.

[How]
Extend the waiting time to 500ms
