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().

This allows us to use smp_cross_call() to trigger a number of different
software generated interrupts, rather than combining them all on one
SGI. Recover the SGI number via do_IPI.

This enables the l2x0 support and ensures that the secondary
CPU can see the page table and secondary data at this point.

Adds core support for the ST-Ericsson U8500
platform. It supports memory mappings, binds to
the existing modules like GIC, SCU, TWD and
local timers and sets up the infrastructure for
the secondary core.
