mfd: wm8997: Update to use maple tree register cache

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.

Update the wm8997 driver to use the more modern data structure.

mfd: arizona: Fixup register table definitions

The regmap register definitions have been a source of many small fixes
as issues are discovered. As such I made a small automated tool to
check these definitions. This patch fixes the issues (mostly harmless)
located by that tool, the issues fall into three catagories:

1) Volatile registers that have a default in the defaults table (default
has been removed from the table since it is redundant)
2) Registers that are marked as volatile but unreadable (register has
been removed from the volatile list since it is obviously not being
used)
3) Registers that arn't readable but have an entry in the defaults
table (again removed since it is redundant)
4) Readable non-volatile registers that are missing a default, these are
dangerous as they won't get synced during a cache sync. Fortunately,
most of them seem to be registers that shouldn't be there (for example
wm5102 had readable registers for DRC2 and ISRC3 which is doesn't have)

Hopefully another tool will be produced to check the actual default
values themselves but that is outside the scope of this patch.

regmap: Use reg_sequence for multi_reg_write / register_patch

Separate the functionality using sequences of register writes from the
functions that take register defaults. This change renames the arguments
in order to support the extension of reg_sequence to take an optional
delay to be applied after any given register in a sequence is written.
This avoids adding an int to all register defaults, which could
substantially increase memory usage for regmaps with large default tables.

This also updates all the clients of multi_reg_write/register_patch.

Merge tag 'sound-4.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
"There are little changes in core part, but lots of development are
found in drivers, especially ASoC. The diffstat shows regmap-related
changes for a slight API additions / changes, and that's all.

Looking at the code size statistics, the most significant addition is
for Intel Skylake. (Note that SKL support is still underway, the
codec driver is missing.) Also STI controller driver is a major
addition as well as a few new codec drivers.

In HD-audio side, there are fewer changes than the past. The
noticeable change is the support of ELD notification from i915
graphics driver. Thus this pull request carries a few changes in
drm/i915.

Other than that, USB-audio got a rewrite of runtime PM code. It was
initiated by lockdep warning, but resulted in a good cleanup in the
end.

Below are the highlights:

Common:
- Factoring out of AC'97 reset code from ASoC into the core helper
- A few regmap API extensions (in case it's not pulled yet)

ASoC:
- New drivers for Cirrus CS4349, GTM601, InvenSense ICS43432, Realtek
RT298 and ST STI controllers
- Machine drivers for Rockchip systems with MAX98090 and RT5645 and
RT5650
- Initial driver support for Intel Skylake devices
- Lots of rsnd cleanup and enhancements
- A few DAPM fixes and cleanups
- A large number of cleanups in various drivers (conversion and
standardized to regmap, component) mostly by Lars-Peter and Axel

HD-audio:
- Extended HD-audio core for Intel Skylake controller support
- Quirks for Dell headsets, Alienware 15
- Clean up of pin-based quirk tables for Realtek codecs
- ELD notifier implenetation for Intel HDMI/DP

USB-audio:
- Refactor runtime PM code to make lockdep happier"
