On some platforms it has been noted that a pop noise can be
witnessed when capturing audio, mainly for first time after a
headset jack has been inserted. This is due to a DC offset in the
Mic PGA and so to avoid this delays are required when powering
up the capture path.
This commit rectifies the problem by adding delays post Mic PGA and
post Mixin PGA. The post Mic PGA delay is determined based on
Mic Bias voltage, and is only applied the first time after a
headset jack is inserted.

Currently when HP detection procedure runs for certain MCLK
frequencies, when PLL is bypassed, the procedure will incorrectly
report Lineout instead of Headphones due to timing incosistencies.
To avoid this problem, the PLL is temporarily enabled (if currently
bypassed and MCLK present) to provide consistent timings for the
procedure, regardless of MCLK frequency.

Currently on some headsets slight pops can be heard during DAPM
power-up/down. This can also be witnessed during the HP detect
procedure. This patch addresses the issue by adjusting DAPM power
sequencing slightly, the introduction of delays and use of
minimum HP gain to avoid such noise artefacts.

Currently if AAD is enabled in the device, during system suspend
the feature remains, regardless of whether the codec is a wake-up
source or not. This means some additional power is being used
which is unnecessary, and can causes issues with some platforms'
IRQ handlers where state changes during system suspend aren't
captured.
This patch updates the driver to disable AAD during suspend, if
we're not a wake-up source, and then re-enables this on resume.

Currently the driver code assumes that MCLK will be present during
the procedure, or if it has control of MCLK then it can make sure
it's enabled. Some platforms however do not provide MCLK to the
driver in this way, and will not leave MCLK enabled when Codec is
in STANDBY state.
This patch adds support for the HP detect procedure when running
from the device's internal oscillator, to ensure all platforms
can make use of this feature correctly.

Currently, if the driver has control of MCLK then it remains
enabled as long as the codec is in STANDBY or above. The MCLK is
only really required in STANDBY when a 3-pole jack is inserted
and the HP detect procedure is required to run.
This patch updates the code to enable/disable the MCLK when moving
between the STANDBY and PREPARE bias level, and when a 3-pole jack
is inserted and HP detection is required, thus saving power at all
other times.
