dev-arm: modify GICv3 ITS default addr
The current default base address for GICv3 ITS stated in RealView is
0x2c120000. The redistributors base address is 0x2c010000; each
instantiated core has an associated redistributor with memory region
size 0x40000 (with GICv4 extension, enabled by default). With 8 cores,
the redistributor range spans to 0x2c210000, creating a conflict with
the ITS address space.
This patch changes the ITS base address to 0x2e010000 which guarantees
no overlapping with the redistributor.
