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 wm8998 driver to use the more modern data structure.

Save a few bytes by removing some registers from the driver that are not
currently used and not intended to be used at any point in the future.

My automated test is back and now can check defaults against the actual
hardware. This patch updates the defaults array for the differences
detected and removes a couple of completely unused registers.

Remove defaults for a bunch of volatile registers and remove
ARIZONA_CTRL_IF_SPI_CFG_1 from the readable list since it doesn't exist
on wm8998 which is I2C only.
