From the datasheet, the only way to meet the lowest power consumption is
to pull low the 'pwdnn' gpio. But if it is low, IC will keep in
reset state, all registers reset to default.
And the power consumption is listed below
1. amp off and 'pwdnn' high => idle state, PVDD = 1mA, DVDD = 7mA
2. amp off and 'pwdnn' low => shutdown state, PVDD < 20uA, DVDD < 15uA
It's the large difference for the consumption current
This fix is to use pm_runtime and regcache to handle 'pwdnn' gpio
control.

The endianness flag is used on the CODEC side to specify an
ambivalence to endian, typically because it is lost over the hardware
link. This device receives audio over an I2S DAI and as such should
have endianness applied.

Update internal ocp level to correct value.
Even the wrong ocp setting can also make the sound output, but the power
cannot match the IC capability.

This drops the rt9210 support due to a race with a new version being
sent out for some incremental changes.
