[PATCH 02/48] KVM: Replace MSR_IA32_TIME_STAMP_COUNTER with MSR_IA32_TSC of msr-index.h

[Avi Kivity <avi@redhat.com>]

From: Jaswinder Singh Rajput <jaswinder@kernel.org>

Use standard msr-index.h's MSR declaration.

MSR_IA32_TSC is better than MSR_IA32_TIME_STAMP_COUNTER as it also solves
80 column issue.
