ASoC: sti-sas: 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").

STIH407_AUDIO_DAC_CTRL (0xa8) is listed before
STIH407_AUDIO_GLUE_CTRL (0xa4), which makes the latter 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.
