        src/sys/arch/x86/x86: tsc.c

Log Message:
Use lfence to serialize rdtsc for VIA Nano and up,  same as Linux do.

Unlike Linux I didn't add a 64-bit guard on assumption that it should work
the same way and the 64-bit version will likely be the preferred one by users.

planning to pull up to netbsd-11, netbsd-10.
