The register map for this device is actually fairly sparse so the rbtree
should be beneficial.

Ensures that we get control of the CODEC earlier and don't try to probe
the card at all if register I/O isn't working.

Helps push the register cache code down out of ASoC and improves resume
times by using the more efficient regmap cache sync code.

With a low frequency SYSCLK and a fast I2C clock register synchronisation
may occasionally take too long to take effect, causing I/O issues. Disable
synchronisation in order to avoid any issues.

These are all to either uncached registers or fixes to register defaults,
in the former case the cache won't do anything and in the latter case
we're fixing things so the cache sync will do the right thing.

Register LDOCTLEN must always be initialized to clear the analog power
control bit, otherwise the analog block will stay deactivated.

Dividers (such as MDAC) are always needed, independent of the codec
being I2S master or slave. Needed on a custom board where the codec has
to be slave.

The two DACs for the front output and the surround/center/LFE/back
outputs are wired up out of phase, so when channels are duplicated,
their sound can cancel out each other and result in a weaker bass
response. To fix this, reverse the polarity of the neutron flow to
the front output.
