ASoC: SOF: ipc4: Support for sending payload along with LARGE_CONFIG_GET

Browse source

[ Upstream commit d96cb0b86d ]

There are message types when we would need to send a payload along with
the LARGE_CONFIG_GET message to provide information to the firmware on
what data is requested.
Such cases are the ALSA Kcontrol related messages when the high level
param_id tells only the type of the control, but the ID/index of the exact
control is specified in the payload area.

The caller must place the payload for TX before calling the set_get_data()
and this payload will be sent alongside with the message to the firmware.

The data area will be overwritten by the received data from firmware.
