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.
