drm/amd/display: Fix DCN32 DPSTREAMCLK_CNTL programming
[Why]
Each index in the DPSTREAMCLK_CNTL register
phyiscally maps 1-to-1 with HPO stream encoder
instance. On the other hand, each index in
DTBCLK_P_CNTL physically maps 1-to-1 with OTG
instance.
Current DCN32 DPSTREAMCLK_CLK programing assumes
that OTG instance always maps 1-to-1 with
HPO stream encoder instance. This is not always
guaranteed and can result in blackscreen.
[How]
Program the correct dpstreamclk instance with
the correct dtbclk_p source.
