ASoC: fsl_sai: MCLK bind with TX/RX enable bit

Browse source

On i.MX8MP, the sai MCLK is bound with TX/RX enable bit,
which means the TX/RE enable bit need to be enabled then
MCLK can be output on PAD.

Some codec (for example: WM8962) needs the MCLK output
earlier, otherwise there will be issue for codec
configuration.

Add new soc data "mclk_with_tere" for this platform and
enable the MCLK output in startup stage.

As "mclk_with_tere" only applied to i.MX8MP, currently
The soc data is shared with i.MX8MN, so need to add
an i.MX8MN own soc data with "mclk_with_tere" disabled.
