commit b45fc97ebcfb27ec250025329a4f79ce5e327ec3 upstream.

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").

tas2783_reg_default[] is grouped by SDCA entity name instead, so the
binary search does not find 120 of its 196 entries.
regcache_reg_needs_sync() then cannot compare those 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.
