ASoC: rt700: 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").

At the end of rt700_reg_defaults[] the 0x83xx entries are interleaved with
the 0x73xx entries they belong to, which leaves 6 of the 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.
