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@chromium.org> BUG=b:111700809 TEST=On grunt: No "Invalid micbias pulse level" in dmesg Change-Id: Ie99a8962e78c68b3f6927d0de34168f265d4efa9 Reviewed-on: https://review.coreboot.org/27613 Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Akshu Agrawal <akshu.agrawal@amd.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
