ASoC: codecs: lpass-{tx,wsa}-macro: fix enum kcontrol accesses

Dawid Wróbel <me@dawidwrobel.com> says:

Both drivers access enumerated controls through value.integer.value[0]
instead of value.enumerated.item[0]. The same bug was fixed in rx-macro
and va-macro in 2022 (bcfe5f76cc40, 0ea5eff7c606); tx-macro and
wsa-macro were missed.

On 64-bit kernels with CONFIG_SND_CTL_DEBUG this trips the elem value
sanity check, and every read of the affected controls fails with
-EINVAL.

Reproduced and fixed on a Xiaomi Mi Pad 5 Pro (SM8250) for tx-macro.
wsa-macro is compile-tested only — that codec is not instantiated on
this hardware.
