src/sys/arch/x86/x86: tsc.c
Log Message:
Update invariant TSC detect code from both Intel and AMD documents.
The best way to check whether the TSC counter is invariant or not is to check
CPUID 8007.
It might be worth to refactor this as a function, given that the code is
replicated in arch/x86/acpi/acpi_cpu_md.c.

Yes, the code can be shared. I'm new to x86 and I'm not familiar
with acpi, so please do it if you can :)
For last few months, I have been reading documents and code around
CPUID and MSR registers. While reading the code, I knew I had to check
ACPI stuff, but I've not done it yet :-
