ASoC: pcm512x: 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").

PCM512x_AUTO_MUTE (page 0, register 59) is listed before
PCM512x_ERROR_DETECT (page 0, register 37) and PCM512x_VCOM_CTRL_2
(page 1, register 9) is listed before the page 0 clocking block, so the
bsearch() descends into the wrong half of the table.  24 of the 45
entries are unreachable, among them every PLL coefficient and clock
divider default.  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.
