drivers/i2c/da7219: Allow disabling micbias-pulse feature
These two da7219_aad properties are optional:
- dlg,micbias-pulse-lvl : Mic bias higher voltage pulse level (mV).
[<2800>, <2900>]
- dlg,micbias-pulse-time : Mic bias higher voltage pulse duration (ms)
When the Mic Bias Higher Voltage feature is not required, firmware should
just not provide the dlg,micbias-pulse-lvl and dlg,micbias-pulse-time
properties.
Signed-off-by: Daniel Kurtz <djkurtz at chromium.org>
BUG=b:111700809
TEST=On grunt:
No "Invalid micbias pulse level" in dmesg
