arm64: dts: r8a7795: Increase the size of GIC-400 mapped registers
There are some requirements about the GIC-400 memory layout and its
mapping if using 64k aligned base addresses like on r8a7795.
See e.g.
http://xenbits.xen.org/gitweb/?p=xen.git;a=commit;h=21550029f709072aacf3b9
Map the whole memory range instead of only 0x2000. This will fix
the issue that some hypervisors, e.g. Xen, fail to handle the
interrupts correctly.
