ASoC: rt715-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
rt715_reg_defaults_sdca[] the CX_CLK_SEL control is listed before the
ADC8_9, ADC10_11 and ADC7_27 mute controls (7 of 78 entries unreachable),
and in rt715_mbq_reg_defaults_sdca[] the AMIC_GAIN_EN CH_08 entry is listed
before the DMIC_GAIN_EN entries (1 of 32 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.
