[PATCH 3/3] ASoC: tegra210_mixer: 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").
TEGRA210_MIXER_ENABLE (0x400) is the last entry of the table, after
TEGRA210_MIXER_PEAKM_RAM_CTRL (0x434), which makes it unreachable.
regcache_reg_needs_sync() then cannot compare it against its default and
reports that a sync is needed, so it is written to the device on every
regcache_sync() even when it was never touched.
Sort the table by register address.
