arm_mpam: Switch to kvzmalloc_objs() for allocation of component cfg
Each component cfg is sized by the size of a per-PARTID multiplied by the
number of PARTIDs. On a platform sized to push the limits of the
specification, the allocation using kzalloc_objs() will consistently
fail. Change to use kvzmalloc_objs() so that large allocations fall back to
vmalloc() based allocations.
