Subject: arm64/kvm: vgic: use SYS_DESC()
Patch-mainline: v4.13-rc1
Git-commit: 0959db6c0b069739ffedf3f6b97644213df586d4
References: bsc#1077761
Almost all of the arm64 KVM code uses the sysreg mnemonics for AArch64
register descriptions. Move the last straggler over.
To match what we do for SYS_ICH_AP*R*_EL2, the SYS_ICC_AP*R*_EL1
mnemonics are expanded in <asm/sysreg.h>.
