This reverts commit 1580ccb6ed9dc76b8ff3e2d8912e8215c8b0fa6d.
The HSYNC/VSYNC polarity of rk3036 HDMI are controlled by GRF.
Without the polarity configuration in GRF, it can be observed from
the HDMI protocol analyzer that the H/V front/back timing output
by RK3036 HDMI are currently not in line with the specifications.
