ASoC: SOF: ipc3: Dump IPC message payload
Dump the IPC message payload if BIT(11) of sof_debug is set and the message
contains more data than just a header.
The header size differs between TX and RX and in case of set_get_data, the
header is always the reply header for the message regardless if it is TX
or RX.
The use of printk(KERN_DEBUG "..."); is on purpose to keep the dmesg output
tidy.
