ASoC: codecs: wc938x: fix accessing array out of bounds for enum type

[ Upstream commit cc587b7c8fbbe128f6bd0dad025a0caea5e6d164 ]

Accessing enums using integer would result in array out of bounds access
on platforms like aarch64 where sizeof(long) is 8 compared to enum size
which is 4 bytes.

Fix this by using enumerated items instead of integers.
