ASoC: adau1761: 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 commit
fd80df352ba1 ("regcache: Add support for sorting defaults arrays").
The table lists the ADAU1761 specific registers (0x4008 and up) before
the block shared with the ADAU1381/ADAU1781, which starts at
ADAU17X1_CLOCK_CONTROL (0x4000), so bsearch() descends into the wrong
half and 28 of the 52 entries are unreachable.
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.
