[PATCH v11 06/43] KVM: arm64: nv: Add include containing the VNCR_EL2 offsets

[Marc Zyngier <maz@kernel.org>]

VNCR_EL2 points to a page containing a number of system registers
accessed by a guest hypervisor when ARMv8.4-NV is enabled.

Let's document the offsets in that page, as we are going to use
this layout.
