ASoC: rt712-sdca-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").

rt712_sdca_reg_defaults[] is grouped by SDCA function instead, so the
binary search does not find 4 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.

One of them is the Mic Array Clock Source 0x1C Sample Frequency Index
control, which a part without that function rejects:

  soundwire_intel.link.0: Msg ignored for Slave 6, addr: 0x8e00

Sort the table by register address.
