446794de8d tsc: Change default tsc calibration method to pmtimer on EFI systems 
On efi systems, make pmtimer based tsc calibration the default over the
pit. This prevents Grub from hanging on Intel SoC systems that power gate
the pit.

461bfab7b7 coreboot: Split parts that are platform-independent. 
We currently assume that coreboot is always i386, it's no longer the case,
so split i386-coreboot parts from generic coreboot code.

a03c1034f6 i386: fix TSC calibration using PIT 
Condition was accidentally reversed, so PIT calibration always failed
when PIT was present and always succeeded when PIT was missing, but in
the latter case resulted in absurdly fast clock.

Reported and tested by Vitaly Kuznetsov <vkuznets@redhat.com>

d43a5ee651 tsc: Use alternative delay sources whenever appropriate. 
PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.

Based on patch by Michael Chang.
