[PATCH 17/17] ASoC: rt1318-sdw: sort the register default table

reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch().  See commit
fd80df352ba1 ("regcache: Add support for sorting defaults arrays").

rt1318_reg_defaults[] is not in address order, so the binary search does
not find 3 of its entries.  regcache_reg_needs_sync() then cannot compare
those against their default and reports that a sync is needed, so they
are written to the device on every regcache_sync() even when they were
never touched.

Sort the table by register address.
