ARM: mach-shmobile: r8a7779: Allow initialisation of GIC by DT
This allows the GIC interrupt controller of the r8a7779 SoC to be
initialised using a flattened device tree blob.
Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

v3
* Fix copy-paste error and use unique reg values for each CPU
v2
As suggested by Mark Rutland
* Add reg and device_type to cpus
* Remove #address-cells from gic
