If an ASoC component device does not have a device tree node, use its
parent's node instead, when looking for a matching DAI based on a
device tree reference.

This allows video device drivers to register a separate child device
for their ASoC side audio functionality.  [And MFDs in general --

The WM8997 and WM5102 codecs need to boost DVFS for higher sample rates.

In theory the ADSP driver should not need to know anything
about the codec it is part of. But the WM5102 needs DVFS
control based on ADSP clocking speed. This was being handled
by bundling part of the knowledge of this into the ADSP driver.

This change moves this handling out of the ADSP driver and
into the WM5102 driver.

The WM5102 and WM8997 codecs have an internal dynamic clock booster.
When this booster is active, the DCVDD voltage must be increased.
If all the currently active audio paths can run with the root SYSCLK
we can disable the booster, allowing us to turn down DCVDD voltage
to save power.

Previously this was being done by having the booster enable bit set
as a side-effect of the LDO1 regulator driver, which is unexpected
behaviour of a regulator and not compatible with using an external
regulator.  [Originally this was documented as a feature of the internal
LDO -- broonie]

This patch exports functions to handle the booster enable and
DCVDD voltage, with each relevant subsystem flagging whether it can
currently run without the booster. Note that these subsystems are
stateless and none of them are nestable, so there's no need for
reference counting, we only need a simple boolean for each subsystem
of whether their current condition could require the booster or will
allow us to turn the codec down to lower operating power.

Also drop the unnecessary comparison in the set_bias_level() callback that
checks if the device is already at the target level. The core already takes
