The CS42L42 has a SoundWire interface for control and audio. This
chain of patches adds support for this.

Patches #1 .. #5 split out various changes to the existing code that
are needed for adding Soundwire. These are mostly around clocking and
supporting the separate probe and enumeration stages in SoundWire.

Patches #6 .. #8 actually adds the SoundWire handling.

idle_bias_on was set because cs42l42 has a "VMID" type pseudo-midrail
supply (named FILT+), and these typically take a long time to charge.
But the driver never enabled pm_runtime so it would never have powered-
down the cs42l42 anyway.

In fact, FILT+ can charge to operating voltage within 12.5 milliseconds
of enabling HP or ADC. This time is already covered by the startup
delay of the HP/ADC.

The datasheet warning about FILT+ taking up to 1 second to charge only
applies in the special cases that either the PLL is started or
DETECT_MODE set to non-zero while both HP and ADC are off. The driver
never does either of these.

Removing idle_bias_on allows the Soundwire host controller to suspend
if there isn't a snd_soc_jack handler registered.

This adds support for using CS42L42 as a SoundWire device.

SoundWire-specifics are kept separate from the I2S implementation as
much as possible, aiming to limit the risk of breaking the I2C+I2S
support.

There are some important differences in the silicon behaviour between
I2S and SoundWire mode that are reflected in the implementation:

- ASP (I2S) most not be used in SoundWire mode because the two interfaces
  share pins.

- The SoundWire capture (record) port only supports 1 channel. It does
  not have left-to-right duplication like the ASP.

- DP2 can only be prepared if the HP has powered-up. DP1 can only be
  prepared if the ADC has powered-up. (This ordering restriction does
  not exist for ASPs.) The SoundWire core port-prepare step is
  triggered by the DAI-link prepare(). This happens before the
  codec DAI prepare() or the DAPM sequence so these cannot be used
  to enable HP/ADC. Instead the HP/ADC enable/disable are done during
  the port_prep callback.

- The SRCs are an integral part of the audio chain but in silicon their
  power control is linked to the ASP. There is no equivalent power link
  to SoundWire DPs so the driver must take "manual" control of SRC power.

- The SoundWire control registers occupy the lower part of the SoundWire
  address space so cs42l42 registers are offset by 0x8000 (non-paged) in
  SoundWire mode.

- Register addresses are 8-bit paged in I2C mode but 16-bit unpaged in
  SoundWire.

- Special procedures are needed on register read/writes to (a) ensure
  that the previous internal bus transaction has completed, and
  (b) handle delayed read results, when the read value could not be
  returned within the SoundWire read command.

There are also some differences in driver implementation between I2S
and SoundWire operation:

- CS42L42 I2S does not runtime_suspend, but runtime_suspend/resume support
  has been added into the driver in SoundWire mode as the most convenient
  way to power-up the bus manager and to handle the unattach_request
  condition, though the CS42L42 chip does not itself suspend or resume.

- Intel SoundWire host controllers have a low-power clock-stop mode that
  requires resetting all peripherals when resuming. This means that the
  interrupt registers will be reset in between the interrupt being
  generated and the interrupt being handled, and since the interrupt
  status is debounced, these values may not be accurate immediately,
  and may cause spurious unplug events before settling.

- As in I2S mode, the PLL is only used while audio is active because
  of clocking quirks in the silicon. For SoundWire the cs42l42_pll_config()
  is deferred until the DAI prepare(), to allow the cs42l42_bus_config()
  callback to set the SCLK.

The chosen clocking configuration must give an internal MCLK (MCLKint)
that is an integer multiple of the sample rate.

On I2S each of the supported bit clock frequencies can only be generated
from one sample rate group (either the 44100 or the 48000) so the code
could use only the bitclock to look up a PLL config.

The relationship between sample rate and bitclock frequency is more
complex on Soundwire and so it is possible to set a frame shape to
generate a bitclock from the "wrong" group. For example 2*147 with a
48000 sample rate would give a bitclock of 14112000 which on I2S
could only be derived from a 44100 sample rate.

Currently, port_prep callback only has commands for PRE_PREP, PREP,
and POST_PREP, which doesn't directly say whether this is for a
prepare or deprepare call. Extend the command list enum to say
whether the call is for prepare or deprepare aswell.

Also remove SDW_OPS_PORT_PREP from sdw_port_prep_ops as this is unused,
and update this enum to be simpler and more consistent with enum
sdw_clk_stop_type.

Note: Currently, the only users of SDW_OPS_PORT_POST_PREP are codec
drivers sound/soc/codecs/wsa881x.c and sound/soc/codecs/wsa883x.c, both
of which seem to assume that POST_PREP only occurs after a prepare,
even though it would also have occurred after a deprepare. Since it
doesn't make sense to mark the port prepared after a deprepare, changing
the enum to separate PORT_DEPREP from PORT_PREP should make the check
for PORT_PREP in those drivers be more logical.
