Use the mtk_pwm_data struction to define different registers
and add MT8183 specific register operations, such as MT8183
doesn't have commit register, needs to disable double buffer
before writing register, and needs to select commit mode
and use PWM_PERIOD/PWM_HIGH_WIDTH.

MT8183 samples on rising and falling edge. It can reduce half data
io.
MT8173 also has those registers. But the hw function is removed.
So MT8173 doesn't support DPI dual edge sample and can't use the
same setting to mt8183.

Pull dpi pins low when dpi has nothing to display. Aovid leakage

Some chips have dpi pins, but there are some chip don't have pins.
So this function is controlled by device tree.
