Hsiao Chien Sung a3f7f7ef4b drm/mediatek: Support "Pre-multiplied" blending in OVL
Support "Pre-multiplied" alpha blending mode on in OVL.
Before this patch, only the "coverage" mode is supported.

As whether OVL_CON_CLRFMT_MAN bit is enabled, (3 << 12)
means different formats in the datasheet. To prevent
misunderstandings going forward, instead of reusing
OVL_CON_CLRFMT_RGBA8888, we intetionally defined
OVL_CON_CLRFMT_PARGB8888 with bit operation again.
