ASoC: rt715: 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 rt715_reg_defaults[] the 0x82xx and 0x83xx entries are
interleaved with the 0x72xx and 0x73xx entries they belong to, and 0x385e
is listed before 0x3859.  This leaves 25 of the 323 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.
