ASoC: tas2552: sort the register default table
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").
TAS2552_OUTPUT_DATA (0x07), TAS2552_PDM_CFG (0x11), TAS2552_PGA_GAIN
(0x12) and TAS2552_BOOST_APT_CTRL (0x14) are listed before
TAS2552_RESERVED_0D (0x0d), TAS2552_LIMIT_RATE_HYS (0x0e) and
TAS2552_CFG_2 (0x02), which leaves 7 of the 21 entries unreachable.
regcache_reg_needs_sync() then cannot compare them 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.
