ASoC: Updates for v3.15

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:

 - Lots of cleanups from Takashi for enumerations; the original API for
   these was error prone so he's refactored lots of code to use more
   modern APIs which avoid issues.
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle.
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues.
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues.
 - DPCM support for Intel Haswell and Bay Trail platforms.
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC.

ASoC: Fixes for v3.14

A few things here:
 - Avoid memory leaks in error cases with DPCM, this code has never been
   that well tested in mainline due to the lack of mainline drivers but
   we now have one queued for the merge window!
 - Fix the N810 audio driver to load when booted with DT since the
   platform was converted to DT during the merge window.
 - Fixes for initialisation of some MFD drivers that are probably unused
   in mainline

The rt5640 driver won't compile without I2C enabled. Hence, the Intel
Haswell and Baytrail+RT5640 ASoC drivers must also depend on I2C, since
these select RT5640.

regmap should handle any byte ordering issues required, it is looking for
a byte stream from the bus, so don't set 16 bits per word. This is likely
to have tested out OK due to use of an unmerged SPI controller driver.

Freeing the current list element while iterating over the list will cause a use
after free since the iterator function will still use the current element to
look up the next. Use list_for_each_safe() and remove the element from the list
before freeing it to avoid this.

Since the CODEC driver could specify its own I/O(read and write)
while registering the CODEC for some reason, maybe the MFDs is
used, etc.

So just do check it, if they are not specified by CODEC driver
then try to set up the default regmap I/O if regmap is used.

Now that all users have been converted to regmap and the config.reg_bits
and config.val_bits can be setted by each user through regmap core API.
So these two params are redundant here.

Since the only control type that left is SND_SOC_REGMAP, so remove it. Drop
the control params and add struct regmap *regmap to simplify the code.

Try to spot locking issues by asserting that the DAPM mutex is held when
it should be. There's a bit of fun due to us not requiring the lock to be
held prior to the card being instantiated which mean we need to wrap the
assert in some paths and this isn't methodical by any stretch of the
imagination.

Now that every DAI has a component we can track the DAIs on a per component
