[PATCH v4 17/18] KVM: arm64: selftests: Replace ARM64_SYS_REG with ARM64_SYS_KVM_REG

From: Raghavendra Rao Ananta
Date: Wed Sep 08 2021 - 21:41:50 EST


With the introduction of ARM64_SYS_KVM_REG, that takes the
system register encodings from sysreg.h directly, replace
all the users of ARM64_SYS_REG, relyiing on the encodings
created in processor.h, with ARM64_SYS_KVM_REG.
