ASoC: meson: g12a-toacodec: Validate written enum values
When writing to an enum we need to verify that the value written is valid
for the enumeration, the helper function snd_soc_item_enum_to_val() doesn't
do it since it needs to return an unsigned (and in any case we'd need to
check the return value).
