drm/bridge/sii8620: fix display of packed pixel modes in MHL2
Currently packed pixel modes in MHL2 can't be displayed. The device automatically recognizes output format, so setting format other than RGB causes failure. Fix it by writing proper values to registers. Tested on MHL1 and MHL2 using various vendors' dongles both in DVI and HDMI mode.
