According to the datasheet rev1.05 Table 5-1:
SDC_N is 1 for HBR/HBR2.
However datasheet wasn't correct.

Generally, DMICs require some delay to wake up to NORMAL state
after clk enabled (WAKE-UP Time), and it varies per dmic chips,
we should ignore the dirty data in this duration.
This patch introduce "start/filter-delay-ms" to skip the pop noise
in the duration, and export this delay to allow user to change it.
* PDM Start Delay Ms
a necessary delay for dmics wake-up after clk enabled, and drop the
dirty data in this duration.
* PDM Filter Delay Ms
after xfer start, a necessary delay for filter to init and will drop
the dirty data in the trigger-START late.
e.g.
/# amixer -c 3 contents
numid=4,iface=PCM,name='PDM Filter Delay Ms'
; type=INTEGER,access=rw------,values=1,min=20,max=1000,step=1
: values=20
numid=3,iface=PCM,name='PDM Start Delay Ms'
; type=INTEGER,access=rw------,values=1,min=0,max=1000,step=1
: values=20
/# amixer -c 3 cset numid=4 30
numid=4,iface=PCM,name='PDM Filter Delay Ms'
; type=INTEGER,access=rw------,values=1,min=20,max=1000,step=1
: values=30

Disable preempt when schedule task timeout work and start hardware.
On heavy system burden case the kthread may be switched out between
starting timeout work and real hardware starting operation and do not
come back for a long time. This will cause unexpected task timeout.
