OVL_CON_CLRFMT_MAN is an configuration for extending color format
settings of DISP_REG_OVL_CON(n).
It will change some of the original color format settings.

Take the settings of (3 << 12) for example.
- If OVL_CON_CLRFMT_MAN = 0 means OVL_CON_CLRFMT_RGBA8888.
- If OVL_CON_CLRFMT_MAN = 1 means OVL_CON_CLRFMT_PARGB8888.

Since OVL_CON_CLRFMT_MAN is not supported on previous SoCs,
It breaks the OVL color format setting of MT8173.
So add fmt_support_man to the driver data of MT8192 and MT8195
to solve the downgrade problem.
