arch-arm: Refactor code to check if gic is GicV2
Refactor code to use cpu_addr only when gic is GicV2 since cpu_addr is
only meanful to GicV2.
Test: Boot Android P successfully with the following command:
M5_PATH=$PWD/fs_files ./build/ARM/gem5.opt
./configs/example/arm/fs_bigLITTLE.py --dtb
$PWD/fs_files/binaries/armv8_gem5_v2_1cpu.dtb --kernel
$PWD/fs_files/binaries/vmlinux --disk $PWD/fs_files/disks/disk.img
--kernel-init "/init" --cpu-type fastmodel --machine-type
VExpressFastmodel --big-cpu-clock "2GHz" --big-cpus 1 --little-cpus 0
--mem-size 8GB --kernel-cmd "earlyprintk=pl011,0x1c090000
