At the moment we have a GIC_ENABLE_V4_EXTN build time variable to
determine whether the GIC interrupt controller is compliant to version
4.0 of the GIC spec or not.
In case of the GIC-600 multichip support we were somewhat abusing that
flag to differentiate between a GIC-700 and GIC-600 implementation
being used in the system.
To avoid a build time dependency on this flag, look at the GICD_IIDR
register and check if the hardware is a GIC-600 or not, to make this
decision at runtime. We then use the values for either GIC-700 or the
GIC-600, respectively.

Add support to configure GIC-600's multichip routing table registers.
Introduce a new gic600 multichip structure in order to support platforms
to pass their GIC-600 multichip information such as routing table owner,
SPI blocks ownership.
This driver is currently experimental and the driver api may change in
the future.
