Volume 255 corresponding to register value 0, the value 0 is default

value, this register will be skipped. So volume 255 isn't set to
register successfully.
The correct fix is to add software reset in runtime_resume, but cs42xx8
has no software reset, the hardware reset gpio pin is used by all the
perpherial device in ARD base board. So need to use another method.
In order to fix it, need to cherry-pick two patch from master branch.
Which will sync all the registers include the register which cache value
equal the default value, And remove regcache_mark_dirty().
Add update value of one register to make the cache_dirty if user press

MLK-11395-1: reset: register gpio-reset driver in arch_initcall
It's a little bit late to register gpio-reset driver at module_init
time, because gpio-reset provides reset control via gpio for other
devices which are mostly probed at module_init time too. And it
becomes even worse, when the gpio comes from IO expander on I2C bus,
e.g. pca953x. In that case, gpio-reset needs to be ready before I2C
bus driver which is generally ready at subsys_initcall time. Let's
register gpio-reset driver in arch_initcall() to have it ready early
enough.
The defer probe mechanism is not used here, because a reset controller
driver should be reasonably registered early than other devices. More
importantly, defer probe doe not help in some nasty cases, e.g. the
gpio-pca953x device itself needs a reset from gpio-reset driver start
working.

Low power idle -> third level idle, only when system is in low bus mode.
In low powe idle mode, below operations will be done:
ARM power off;
AHB freq lower to 3MHz;
PERCLK freq lower to 6MHz;
MMDC freq lower to 1MHz;
Anatop will be put into low power mode, and regular band-gap will
be off and low power band-gap will be enabled instead.
Also, in low power idle mode, 24MHz XTAL power will be off and 24MHz clk

since BCH use AXI bus transfer data through fabric, need to enable this

This patch enabled this clock for all i.MX6 platforms and has been
