Subject: [PATCH] sm6250-common: Add a shim to silence prebuilt audio HAL

For some reason Xiaomi built audio HAL with "very very verbose logging"
enabled [1] and it spams really too much. Until Xiaomi builds audio HAL
with sane logging level or a way to resolve OSS audio HAL issues is
found, just shim the whole log function to return nothing.
