[PATCH v2 16/22] arm64: cpucaps: Rename GICv3 CPU interface capability

[Lorenzo Pieralisi <lpieralisi@kernel.org>]

In preparation for adding a GICv5 CPU interface capability,
rework the existing GICv3 CPUIF capability - change its name and
description so that the subsequent GICv5 CPUIF capability
can be added with a more consistent naming on top.
