ARM: add 32bit support to GICv3
Implement the system and memory-mapped register accesses in asm/arch_gicv3.h for 32bit architectures. This patch is a straightforward translation of the arm64 header. 64bit accesses are done in two times and don't need atomicity: TYPER is read-only, and the upper-word of IROUTER is always zero on 32bit architectures.
