In order to improve 4K resolution performance,
we have to enhance the HDMI driving currend
when clock rate is greater than 165MHz.

The mtk_hdmi_send_infoframe have to
be run after PLL and PIXEL clock of HDMI enable.
Make sure that HDMI inforframes can be sent
successfully.

if MT8173 display module can support 4K HDMI output,
we have to adjust VENCPLL clock from default 660MHz
to 800MHz.

This is MT8173 gamma & dither support PATCH v3, based on 4.7-rc1.
Changes since v2:
-Modify defines to match the register field names in the MT8173 datasheet
-Made dithering function support hardware mirroring well on two monitor.

Hi, Daniel,
Thank you for your suggestion, I will modify that to use the atomic
