Add a custom implementation of regmap read/write callbacks using the SPI
bus. This allows them to be performed at a lower SCLK rate than data
reads. Previously, all SPI transfers were being performed at a lower
speed, but with this change sample data is read at the max bus speed
while the register reads/writes remain at the lower rate.
Also remove .can_multi_write from the AD4695 driver's regmap_configs, as
this isn't implemented or needed.

Found a couple more bugs after some testing. I'll wait until EOD on
Wednesday to send a v2, in case there are any other review comments.
