Sugar Zhang 385f6d70a7 ASoC: rockchip: i2s: Add support for clk compensation
This patch introduces a method to handle clk drift and compensation.

e.g:

/# amixer contents
numid=1,iface=PCM,name='PCM Clk Compensation In PPM'
; type=INTEGER,access=rw------,values=1,min=-1000,max=1000,step=1
: values=0

/# arecord -D hw:0,0 --period-size=1024 --buffer-size=4096 -r
16000 -c 2 -f s16_le /dev/zero &

/# amixer -- cset numid=1 -10
numid=1,iface=PCM,name='PCM Clk Compensation In PPM'
; type=INTEGER,access=rw------,values=1,min=-1000,max=1000,step=1
: values=-10

/# amixer -- cset numid=1 10
numid=1,iface=PCM,name='PCM Clk Compensation In PPM'
; type=INTEGER,access=rw------,values=1,min=-1000,max=1000,step=1
: values=10
