ARM: GIC: Remove MMIO address from gic_cpu_init, rename to gic_secondary_init

We don't need to re-pass the base address for the CPU interfaces to the
GIC for secondary CPUs, as it will never be different from the boot CPU
- and even if it was, we'd overwrite the boot CPU's base address.

Get rid of this argument, and rename to gic_secondary_init().
