Probe for GICv3 re-distributors on core bring-up
The GICv3 distributor can have more ports than CPUs are available in the system. Probe all re-distributors and use the matching affinity levels as specified by each core and re-distributor to decide which re-distributor to use with which CPU core. If a core cannot be matched with a re-distributor, the core panics and is placed in an endless loop. Change-Id: Ie393cfe07c7449a2383959e3c968664882e18afc
