ASoC: cs35l41: Combine adjacent register writes

BugLink: https://bugs.launchpad.net/bugs/1965496
cs35l41 is often connected over I2C which is a very slow bus, as such
timings can be greatly improved combining writes where acceptable.
Update several points where the driver does multiple register writes
when a single one would suffice.
