[PATCH 01/17] ASoC: rt274: 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").

Four entries were appended to the end of rt274_reg[] instead of being
inserted at their sorted position, which leaves 7 of the 33 entries
unreachable for the binary search.  regcache_reg_needs_sync() then cannot
compare them 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.
