clk: mediatek: implement MUX_FLAGS and MUX_MIXED_FLAGS macro
Some simple MUX might require flags to specify the parent source.
Implement MUX_FLAGS as a variant of the MUX macro that takes custom
flags as last arg.
Also implement MUX_MIXED_FLAGS for PARENT_MIXED implementation and
MUX_MIXED with no additional flags.
