drm/amd/display: Set max TTU on DPG enable
[WHY]
There is a bug in HW that causes P-State to hang when DPG is enabled in
certain conditions.
[HOW]
The solution is to force MIN_TTU_VBLANK register to maximum value
whenever DPG has been enabled.
Make stream do a full update on test pattern change, so that the TTUs
get updated.
When DPG is enabled, update the ttu_regs.min_ttu_vblank field of each
pipe in the stream's topology to the maximum value (0xffffff).
v2: squash in build fix for when DCN is not defined (Alex)
