cpufreq: Always allow update of user policy

In the cases where the system boots up in a constraint with policy min and
max lower than cpuinfo min/max, and user tries to set a higher user
policy min, the value would be overridden during the verifying the
limits.

Once user initiates the sysfs write the previous user policy is
maintained in policy min and max thus changing the limits for verification
of the current policy. Once the verification is completed restore the
current user policy min/max with the updated values if any. This would take
care of cases uwhere user policy min/max input is higher/lesser than the
current min and max.

mfd: wcd9xxx: Add support for REPEAT_CHANGE_VALUE

Slimbus supports ability to write upto 16 bytes to the same register as
one transaction on the bus through REPEAT_CHANGE_VALUE slimbus message.
Add support to write codec register with multiple values using
REPEAT_CHANGE_VALUE. Not all sizes from 1 to 16 are supported by such a
message, add support in driver to be able to write all sizes from 1 to
16 by splitting the register writes of unsupported sizes into multiple
writes of supported sizes.

ASoC: wcd9xxx: Don't enable micbias if headset is removed

If special headset is removed, the callback to
disable micbias will be called, as micbias is
always on with special headset. Mbhc driver
checks a flag, used to disable/enable micbias
for special headset, to make sure micbias is
not disabled by recording. If this flag is not
updated properly before the callback is called
while the headset is removed, it can cause that
micbias is left enabled.

ASoC: wcd9320: Update condition to disable HPH PA after impedance detection

For headsets with threshold on mic, the flag hph_pa_dac_state gets
cleared once they are re-inserted into headphone jack with hph pas
are still ON. This causes impedance detection to disable the PA after
impedance computations. This will result into audio mute. Avoid the audio
mute by updating the condition to disable PAs.

If micbias is enabled during impedance detection, it can result into pop

used for impedance detection measurements, it is safe to disable the

ASoC: wcd9xxx: Correct wrong check conditions

1) For targets where micbias is shared, we do not
use vddio to identify special headset. We want
micbias to be enabled always with any headset
inserted for such targets. Currently, if headset is
inserted during recording, we check for this vddio
flag as well. Since, it is null for the above mentioned
targets, we never touch the code to enable micbias
always for any type of headset.

2) Again for the above mentioned targets, if micbias
is enabled by voice call, and we insert the headset.
Now if headset is removed, we try force diable of
micbias. This results in Tx mute. The count to disable
micbias needs to be corrected.
