staging: fsl-mc: Add new flags field to MC command header
The Management Complex (MC) binary interface added a new "flags" field to the command header. Add the definitions for this field in preparation for adding the new cmd_flags parameter to all MC interface APIs. Signed-off-by: J. German Rivera <German.Rivera@freescale.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
