bus: fsl-mc: Some apis are made public for vfio
Some of the APIs and data-structures are required for VFIO. This patch moves dprc.h to public header files. Also some APIs of mc-bus are made public for vfio. Signed-off-by: Bharat Bhushan <Bharat.Bhushan@nxp.com> Signed-off-by: Laurentiu Tudor <laurentiu.tudor@nxp.com>5.4-rM2-2.2.x-imx-squashed
