x86: c1e_idle: don't mark TSC unstable if CPU has invariant TSC
Impact: Functional TSC is marked unstable on AMD family 0x10 and 0x11 CPUs.
This would be wrong because for those CPUs "invariant TSC" means:
"The TSC counts at the same rate in all P-states, all C states, S0,
or S1"
(See "Processor BIOS and Kernel Developer's Guides" for those CPUs.)
[ tglx: Changed C1E to AMD C1E in the printks to avoid confusion
with Intel C1E ]
