Subject: [PATCH 2/5] ASoC: SOF: mediatek: mt8186: Use snd_sof_ipc_process_reply() helper

Function mt8186_get_reply() performs practically the same operation
as the common snd_sof_ipc_get_reply() helper: removing the custom
function allows us to simply perform a call to the sof-priv helper
snd_sof_ipc_process_reply(), simplifying and shortening this driver
and getting all the benefits of using a common API.
