[PATCH 2/3] ASoC: cs35l45: 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").
cs35l45_defaults[] lists the DSP1_RX*_RATE and DSP1_TX*_RATE registers
(0x02b80080 - 0x02b802b8) in the middle of the table, ahead of entries with
much lower addresses, so the binary search does not find 36 of its 73
entries. 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 the table by register address.
