ASoC: wcd9304: Wait enough time during mbhc calibration

If mbhc micbias has a capacitor which is large enough to delay micbias
voltage ramp up/down, initial calibration also needs to delay enough time
after changing mux to be able to calibrate ground and micbias voltage
accurately.  Increase delay to 50ms during calibration and improve
calibration accuracy.

msm: mdm2: Decrease leakage before QSC power-up

Cleanup of IPC gpios for driver strength and toggle
AP2MDM_STATUS only after AP2MDM_KPD_PWR is toggled, this
will decrease the leakage from MSM to QSC before QSC
powering up.

wcnss: Add support to download calibrated data

WCNSS Firmware needs raw NV data (settings & some register values),
to do the power-on calibration. Once firmware does the power-on
calibration; it can then re-use the calibrated data. And it need not
do the calibration again when the next time it boots. WCNSS sends this
calibrated data to Apps; and Apps saves this into a persistent area.
And in the subsequent bootup, Apps sends the calibrated data to WCNSS.

Add interfaces to read calibrated data; and also add inteface to write
calibrated data to platform driver.

wcnss: Prevent access to WCNSS driver after a failure

Once the WCNSS driver trigger fails, the WCNSS platform driver main

should be prevented after this.
