ASoC: codecs: lpass-va-macro: switch cache to REGCACHE_MAPLE

REGCACHE_FLAT hides missing-default reads by returning the zero-
initialised cache slot instead of doing a bus read.  The caller
can't tell that value apart from a real hardware value, so any
un-defaulted, readable, non-volatile register that gets read
silently returns wrong data.  Since commit e062bdfdd6ad ("regmap:
warn users about uninitialized flat cache") regmap dev_warn_once()s
the first such miss, but any subsequent miss stays silent.

Switch to REGCACHE_MAPLE.  A cache miss returns -ENOENT and the
regmap core falls back to a real bus read, so the caller always
gets the true hardware value.  Write-cache behaviour is unchanged.
