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.
