80b949f332 ASoC: rt9120: Use pm_runtime and regcache to optimize 'pwdnn' logic 
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.

80827c123f ASoC: rt9120: Add endianness flag in snd_soc_component_driver 
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.
