drm/bridge: synopsys: dw-hdmi-qp: Fix frl switch error when switching resolution and color at the same time

Browse Source 
When switching resolution and color at same commit, current

not run properly if switching from tmds resolution to frl resolution.
So we need to add the judgment of the resolution before and after
the switch.
