ASoC: SOF: ipc4-topology: Correct data structures for the SRC module 

Separate the IPC message part as struct sof_ipc4_src_data. This struct
describes the message payload passed to the firmware via the mailbox.

It is not wise to be 'clever' and try to use the first part of a struct
as IPC message without marking the message section as packed and aligned.
