Patrick Rudolph 142f92bf04 drivers/arm: Implement acpi_fill_madt
Fill the MADT table in the GIC driver and armv8 CPU driver to
drop SoC specific code. While the GIC only needs devicetree
data, the CPU driver needs additional information stored in
the cpu_plat struct.

While on it update the only board making use of the existing
drivers and writing ACPI MADT in mainboard code.

TEST: Booted on QEMU sbsa-ref using GICV3 driver model generated MADT.
      Booted on QEMU raspb4 using GICV2 driver model generated MADT.

config CPU
bool "Enable CPU drivers using Driver Model"
help
This allows drivers to be provided for CPUs and their type to be
specified in the board's device tree. For boards which support
multiple CPUs, then normally have to be set up in U-Boot so that
they can work correctly in the OS. This provides a framework for
finding out information about available CPUs and making changes.
