[PATCH 03/18] KVM: ARM64: Add offset defines for PMU registers

[shannon.zhao at linaro.org]

From: Shannon Zhao <shannon.zhao at linaro.org>

We are about to trap and emulate acccesses to each PMU register
individually. This adds the context offsets for the AArch64 PMU
registers and their AArch32 counterparts.
