[PATCH 03/22] drm/amd/display: fix k1 k2 divider programming for phantom streams

[Qingqing Zhuo]

From: Aurabindo Pillai <aurabindo.pil...@amd.com>

[Why & How]
When k1 and k2 divider programming logic is executed for a phantom
stream, the corresponding master stream should be used for the
calculation. Fix the if condition to use the master stream for checking
signal type instead of the phantom stream.
