In order to achieve better DMA performance and reduce download time for
firmware and library, it is recommended to disable dynamic clock and
power gating. In some scenarios, DMA may wait to accumulate more data and
last chunk of data never gets completed if dynamic clock and power
gating is kept enabled.

This patch adds support to disable/enable dynamic clock and power gating
and use it during firmware and library download.

Change the default quirk settings to enable jack-detect, analog mics.

The old default input mapping of DMIC for non Bay Trail CR devices seems
like a poor default as I'm not aware of any Intel SST + rt5651 using
devices with a DMIC.

All Cherry Trail devices using the bytcr_rt5651 machine driver seem to be
modelled after BYT-CR devices, And the only non CR Bay Trail devices with
a rt5651 codec I'm aware of are the Minnow boards for which we already have
board specific quirks. So it seems better to me to use the BYT-CR defaults
everywhere.

This e.g. makes the Chuwi Hi8 Pro (CWI513) work ootb without needing a
quirk.

Despite its name being prefixed with bytcr, before this commit the
bytcr_rt5651 machine driver could not work with Bay Trail CR boards,
as those only have SSP0 and it only supported SSP0-AIF1 setups.

This commit adds support for this, autodetecting AIF1 vs AIF2 based on
BIOS tables.

While at it also add support for SSP2-AIF2 setups, as that requires only
minimal extra code on top of the code adding SSP0-AIF1 / SSP0-AIF2 support.

Note this code is all copy-pasted from bytcr_rt5640.c. I've looked into
merging the 2 machine drivers into 1 to avoid copy-pasting, but there are
enough subtile differences to make this hard *and* with all the quirks the
machine driver already is full with if (variant-foo) then ... else ...
constructs adding more of these is going to make the code unreadable.

The idea behind exporting rt5651_apply_properties(), was for it to be used
on platforms where the platform code may need to add device-properties,
rather then relying only on properties set by the firmware. The platform
code could then call rt5651_apply_properties() after adding properties to
make sure that the codec driver was aware of the new properties.

But this is not necessary, as long as we do all property parsing from
the codec component-driver's probe function (or later) then the machine
driver can attach properties before calling snd_soc_register_card and
calling rt5651_apply_properties() for ordering reasons is not necessary.

This commit makes rt5651_apply_properties() private and adds 2 comments
documenting that all property parsing must be done from the codec
component-driver's probe function.

To determine if a plugged in jack is a headset (speakers + mic) or
headphones (mic contact shorted to ground) we use the micbias1 OVer Current
Detect (OVCD) functionality.

For this to work we need to have a micbias current to actually cause an
overcurrent condition when headphones are plugged in, so jack-type
detection requires both the LDO and micbias1 supplies to be on.

Before this commit there were 2 issues with the handling of this:
1) The LDO supply was force-enabled twice and never disabled again even
though it only needs to be forced on when doing jack-type detection
2) micbias1 was not force-enabled, and thus may be off when doing jack-type
detection

This commit fixes both by force-enabling the LDO and micbias1 supplies
before checking for an overcurrent condition and disabling them afterwards.

Note that both supplies will still get turned on normally (and OVCD will
protect against overcurrent) when the micbias1 is enabled normally because
the user has activated a sound stream recording from the mic.
