Miles Chen 2268f190af drm/mediatek: Fix mtk_cec_mask() 
[ Upstream commit 2c5d69b0a141e1e98febe3111e6f4fd8420493a5 ]

In current implementation, mtk_cec_mask() writes val into target register
and ignores the mask. After talking to our hdmi experts, mtk_cec_mask()
should read a register, clean only mask bits, and update (val | mask) bits
to the register.
