ASoC: rt711-sdca: sort the register default tables
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").
Both tables group the entries by SDCA entity instead: in
rt711_sdca_reg_defaults[] the CS01 sample frequency index is listed before
the FU05 controls (1 of 54 entries unreachable), and in
rt711_sdca_mbq_defaults[] the MIC_ARRAY FU1E volumes are listed before the
JACK_CODEC FU0F volumes (2 of 25 entries unreachable).
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 both tables by register address.
