ASoC: tas2780: sort the register default table

Browse source

reg_defaults must be sorted by ascending register address, as
regcache_lookup_reg() locates entries in it with bsearch().  See commit
fd80df352b ("regcache: Add support for sorting defaults arrays").

TAS2780_DVC (0x1a) is listed before TAS2780_CHNL_0 (0x03), which makes
it unreachable.  regcache_reg_needs_sync() then cannot compare it
against its default and reports that a sync is needed, so it is written
to the device on every regcache_sync() even when it was never touched.

Sort the table by register address.
