35 support this, MT6577/MT6595/MT8127 do not support.
For example, If want to use I2C4/5/6 pins on MT8135 just need to enable
the pinmux, else if want to use I2C pins on PMIC(MT6397) need to add
"mediatek,have-pmic" property in the .dts file of each platform.

We haven't implement this yet, we will do this in the separate patch.
MT8135 can control I2C pins on PMIC(MT6397) by setting the i2c registers in
MT8135 side. In this case, driver should set OFFSET_PATH_DIR bit first, the
operation on other registers are still the same.
