ASoC: SOF: ipc3: Implement the set_get_data IPC ops 
Add the implementation for the set_get_data callback for handling large
data set and get.

The set_get_data() in IPC3 can be used only for component messages. The
function expects the caller to prepare the message behind the data pointer
for sending/receiving data. The callback only implements the needed code
to be able to split up a message if needed for transfer.

The set_get_data ops is based on the existing
snd_sof_ipc_set_get_comp_data() and sof_set_get_large_ctrl_data() but made
it generic entry point.
