ASoC: SOF: uapi: header: Update sof_abi_hdr doc for IPC4 use
With IPC4 the sof_abit_hdr is only used between user space
(and in topology) and kernel.
The same abi header is used with small differencies like different
magic number and the type field have slightly different name, but
similar function in IPC4 (param_id).
Update the kernel documentation to highlight the differences.
