[PATCH 03/16] ASoC: codecs: tx-macro: fix accessing array out of bounds for enum type

[Srinivas Kandagatla]

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.

Also few return value of put functions, so that change notifications are
sent correctly.

Fixes: c39667ddcfc5 ("ASoC: codecs: lpass-tx-macro: add support for lpass tx macro")
