arm_fpga: Add support for topology self-discovery
As secondary cores show up, they populate an array to
announce themselves so plat_core_pos_by_mpidr() can
return an invalid COREID code for any non-existing
MPIDR that it is queried about.
The Power Domain Tree Description is populated with
a topology based on the maximum harcoded values.
