[PATCH 2/3] ASoC: tegra210_i2s: sort the Tegra264 register default table

[Peter Ujfalusi <peter.ujfalusi@linux.intel.com>]

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").

TEGRA264_I2S_ENABLE (0x100), TEGRA264_I2S_RX_FIFO_WR_ACCESS_MODE (0x30)
and TEGRA264_I2S_TX_FIFO_RD_ACCESS_MODE (0xb0) are listed at the end of
the table, after TEGRA264_I2S_TIMING (0x130), which leaves 4 of the 9
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.
