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 reset code in i2c_probe only resets the AAD part of
the device and not the entire codec. This patch updates the driver
to resolve this and ensures that if the codec is still active from
a previous boot then the audio paths are powered down prior to
reset.

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.

The expected MCLK frequency ranges and the associated dividers
are updated to improve PLL locking in a corner scenario, with low
MCLK frequency near an input divider change boundary.

PLL mode based on 32KHz master clock not supported in
AB silicon so remove support from the driver.

In AB silicon, the internal LDO is not supported so remove
DT and driver references to this (digital voltage direct from
'VDD' supply)
