Audio is distorted during first 3 secs on headset record
while doing device switch from dmic to headset mic.
Disable BCS before slow insertion detection and enable it
afterwards to resolve the issue.

1ms delay is needed for impedance detection after disabling hph
surge. Add delay for wcd937x and wcd938x.

If surge protection is enabled, it interferes with HPHL
and does not give proper impedance for high impedance cable.
Disable surge protection before impedance detection and
enable it again after impedance detection on wcd937x and wcd938x.

Mic bias value is needed in case of special headset
detection logic and the same needs to be read and stored
from device tree to be used by mbhc driver.

Some alsa API are removed in kernel-4.19 which would cause
codec driver compile failure. Update codec driver to fix it.

MICBIAS1 is mapped to MICB2_VOUT. Replace it with
MICBIAS2 as MICBIAS2 is used for mbhc detect.

If headset is connected during SSR, after recovery mbhc
driver expects a new detection event as the driver is reinitialized.
Reset detection type to insertion to retrigger a hw interrupt
for mbhc driver.

Bulk read api does not work properly for swr regmap,
causing failure/delay in impedance detection.
Use regmap read api to avoid the issue.
