All the IRQs for DPAA2 objects in the same DPRC must use
the ICID of that DPRC, as their device Id in the GIC-ITS.
Thus, all these IRQs must share the same ITT table in the GIC.
As a result, a pool of IRQs with the same device Id must be
preallocated per DPRC (

to use an fsl_mc_device pointer instead.
So, this change replaces the 'resource' field in the fsl_mc_io
object with 'dpmcp_dev'. Also, it changes parameter 'resource' of
fsl_create_mc_io() to be an fsl_mc_device pointer instead.

change does not affect other components since fsl_mc_io is an opaque
type.
