ASoC: rt298: 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 rt298_reg[] instead of being
inserted at their sorted position and the 0x01470100 entry is listed after
0x01470c00, which leaves 7 of the 39 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.
