KVM: x86: Simplify and comment kvm_get_time_scale()
The kvm_get_time_scale() function was entirely opaque. Add comments
explaining what it does: compute a fixed-point multiplier and shift for
converting TSC ticks to nanoseconds via pvclock_scale_delta().
Rename the local variables from the cryptic tps64/tps32/scaled64 to
base_hz_u64/base32/scaled_hz_u64 to make the code self-documenting.
The "tps32" name stood for "Ticks Per Second" but was misleading since
it held the shifted base frequency, not a tick count.
No functional change.
