ext_manifest: add simple config data element with IPC_MSG_SIZE
To avoid lots of single value structures this will introduce config data element which will contain several simple token/value pairs At initial version it will contain IPC_MSG_SIZE elem which will inform kernel about maximum IPC msg size Signed-off-by: Adrian Bonislawski <adrian.bonislawski@linux.intel.com>
