staging: fsl-mc: up-rev dpbp binary interface to v2.0
Add cmd_flags parameter to all dpbp APIs to comply with the dpbp 2.0 MC interface. Updated MC version major number. Pass irq args in struct instead of separate args. Signed-off-by: J. German Rivera <German.Rivera@freescale.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
