From: Peter Ujfalusi <peter.ujfalusi@linux.intel.com>

We only print out the header information of an IPC message in debug level,
either in verbose or non verbose way (Kconfig option).

On top of the header information the message itself can help reproducing
and identifying issues.

BIT(11) can be used to request a message payload dump if it is supported
by the IPC implementation.

Since IPC message payload printing is only implemented for IPC4, the flag
will not have any effect to IPC3 for now.
