xen: Prepare common code for Xen PVH support
...
Some common code needs to be special cased for Xen PVH mode. This hits
mostly Xen PV mode specific areas.
Split include/grub/i386/pc/int_types.h off from
include/grub/i386/pc/int.h to support including this file later from
xen_pvh code without the grub_bios_interrupt definition.
Move definition of struct grub_e820_mmap_entry from
grub-core/mmap/i386/pc/mmap.c to include/grub/i386/memory.h in order
to make it usable from xen_pvh code.

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.

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.
