Now that the GIC properly uses IRQ domains, kill off the per-platform
routing tables that were used to make the GIC appear transparent.

This includes:
 - removing the mapping tables and the support for applying them,
 - moving GIC IPI support to the GIC driver,
 - properly routing the i8259 through the GIC on Malta, and
 - updating IRQ assignments on SEAD-3 when the GIC is present.

Platforms no longer will pass an interrupt mapping table to gic_init.
Instead, they will pass the CPU interrupt vector (2 - 7) that they
expect the GIC to route interrupts to.  Note that in EIC mode this
value is ignored and all GIC interrupts are routed to EIC vector 1.

on MTI's site. Currently, the M14K family of cores is what
the SEAD-3 is utilised with.

None of these files are using modular infrastructure, and build
tests reveal that none of these files are really relying on any
implicit inclusions via. module.h either.  So delete them.
