ASoC: fsl_easrc: 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").

The four REG_EASRC_RRL() entries are listed as a block before the four
REG_EASRC_RRH() ones, but the two registers of a context alternate in
the address map (RRL(n) at 0x110 + 8 * n, RRH(n) at 0x114 + 8 * n).
This leaves REG_EASRC_RRL(1), REG_EASRC_RRL(2) and REG_EASRC_RRL(3)
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.
