ASoC: cs35l41: 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 commitfd80df352b("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.
