ASoC: rt712-sdca-dmic: sort the register default table

Browse source

reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch().  See commit
fd80df352b ("regcache: Add support for sorting defaults arrays").

rt712_sdca_dmic_reg_defaults[] is grouped by SDCA entity instead, 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.
