Align mpc8610_hpcd with p1022_ds on getting codec node by just calling
of_parse_phandle.  The bonus point of doing that is we can save
exporting get_node_by_phandle_name() when we consolidate the common
bits between mpc8610_hpcd and p1022_ds into a module, which can be
shared by more machine drivers added later.

SET_SYSTEM_SLEEP_PM_OPS writes .poweroff = *_resume once. Then we overwrite it
again explicitly as .poweroff = snd_soc_poweroff. Even though it works, as the
second one overwrites the first one, this is not the correct way. Fix this by
expanding SET_SYSTEM_SLEEP_PM_OPS in our structure.

Chip designers frequently include things like the enable and disable
controls for algorithms in the register blocks which also hold the
coefficients. Since it's desirable to split out the enable/disable
control from userspace the plain SND_SOC_BYTES() isn't optimal for
these devices.

Add a SND_SOC_BYTES_MASK() which allows a bitmask from the first word
of the block to be excluded from the control. This supports the needs
of devices I've looked at and lets us have a reasonably simple API.
Further controls can be added in future if that's needed.

Allow devices to export blocks of registers to the application layer,
intended for use for reading and writing coefficient data which can't
usefully be worked with by the kernel at runtime (for example, due to
requiring complex and expensive calculations or being the results of
callibration procedures). Currently drivers are using platform data to
provide configurations for coefficient blocks which isn't at all
convenient for runtime management or configuration development.

Currently only devices using regmap are supported, an error will be
generated for any attempt to work with a byte control on a non-regmap
device. There's no fundamental block to other devices so support could
be added if required.

New interfaces to allow other subsystems to gather information about the
regmap, allowing them to build further subsystem specific generic
features on top of the regmap.

Merged into ASoC in order to allow us to implement SND_SOC_BYTES_MASK()
controls which need to know the word size of the underlying registers.
