ASoC: SOF: ipc4-control: Keep the payload size up to date

Browse source

[ Upstream commit ebcfdbe4ad ]

When the bytes data is read from the firmware, the size of the payload
can be different than what it was previously.
For example when the topology did not contained payload data at all for the
control, the data size was 0.
For get operation allow maximum size of payload to be read and then update
the sizes according to the completed message.

Similarly, keep the size in sync when updating the data in firmware.

With the change we will be able to read data from firmware for bytes
controls which did not had initial payload defined in topology.
