[PATCH 1/3] ASoC: cs35l41: 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").

cs35l41_reg[] lists CS35L41_BSTCVRT_PEAK_CUR (0x3808) after
CS35L41_BSTCVRT_COEFF (0x3810) and CS35L41_BSTCVRT_SLOPE_LBST (0x3814), so
the binary search does not find those two entries.
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.
