ASoC: mediatek: add MT7622 AFE support
This patch adds support for the MT7622 AFE which reuses MT2701 driver.

We also introduce the 'struct mt2701_soc_variants' to differentiate
between the SoC generations as there might be other (existing or future)
chips that use the same binding and driver, then being a little more
abstract could help in the long run.

ASoC: mediatek: rework clock functions for MT2701
Reworks clock part to make it more reasonable. The current changes are:

- Replace regmap operations by CCF APIs. Doing so, we just need to handle
  the element clocks and can also get accurate information via CCF.

- Rename clocks to make them more generic so that the future revisions
  of the IP can adapt gracefully.

- Regroup 'aud_clks[]' by usage - the basic needs and I2S parts:

  The new code just keep the common clocks in array and let SoC self decide
  I2S numbers - If future chips have different sets of channels we will
  add a little more abstract here.

  Moreover, this patch moves I2S clocks to the struct mt2701_i2s_data
  so that we can easily manage them when calls .prepare() and .shutdown().

Garlic Tseng 43a6a7e710 ASoC: mediatek: add mt2701 platform driver implementation.
Add mt2701 platform driver implementation for playback and capture.
The implement follow DAPM structure (memory interface as FE and I2S
as BE).
Because of the hardware design, i2s out required to be enabled when
we need to enable i2s in. This patch includes the implementation.
