drm/amdgpu: Fix hdmi deep color support.
When porting the hdmi deep color detection code from radeon-kms to amdgpu-kms apparently some kind of copy and paste error happened, attaching an else branch to the wrong if statement. The result is that hdmi deep color mode is always disabled, regardless of gpu and display capabilities and user wishes, as the code mistakenly thinks that the display doesn't provide the required max_tmds_clock limit and falls back to 8 bpc. This patch fixes deep color support, as tested on a R9 380 Tonga Pro + suitable display, and should be backported to all kernels with amdgpu-kms support.
