drm: bridge: icn6211: Fix HFP_HSW_HBP_HI and HFP_MIN handling
The HFP_HSW_HBP_HI register must be programmed with 2 LSbits of each
Horizontal Front Porch/Sync/Back Porch. Currently the driver programs
this register to 0, which breaks displays with either value above 255.
The HFP_MIN register must be set to the same value as HFP_LI, otherwise
there is visible image distortion, usually in the form of missing lines
at the bottom of the panel.
Fix this by correctly programming the HFP_HSW_HBP_HI and HFP_MIN registers.
