  This serial of patches are adding support of mt2701/mt2712.
there are many changes and HW improvement between mt8173 and
mt2701/mt2712, below is a list of these changes:
  1. enlarge CLKDIV bits from 8 to 12
  2. remove the PAD_TUNE register and add a new PAD_TUNE0 register
  3. add data sync and async fifo feature
  4. add busy_check feature
  5. add stop_clk fix
  6. add enhance_rx support
  7. add a seperate CG of source clock

mt2712 supports full of these features, mt2701 supports part of it, and
add a "mediatek,latch-ck" to work-around as it do not support stop-clk
fix.

Note: As Pinctrl/CCF are not ready now, so that current patches do not
include DTS part.
