[PATCH v4 6/8] ARM: Make CONFIG_CPU_V7 valid for 32bit ARMv8 implementations

[Zaid Al-Bassam]

From: Marc Zyngier <marc.zyngier at arm.com>

ARMv8 is a superset of ARMv7, and all the ARMv8 features are
discoverable with a set of ID registers. It means that we can
use CPU_V7 to guard ARMv8 features at compile time.

This commit simply amends the CPU_V7 configuration symbol comment
to reflect that CPU_V7 also covers ARMv8.
