[PATCH 16/17] ASoC: rt1318: sort the register default table

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

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").

The 0xdd93 and 0xdd94 entries are listed after 0xddc8 in rt1318_reg[],
which leaves them 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.
