ASoC: tegra210_i2s: 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_I2S_ENABLE (0x80) is listed after TEGRA210_I2S_CG (0x88) and
TEGRA210_I2S_TIMING (0xa4), so both it and TEGRA210_I2S_TIMING are
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.
