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.

7da036bbcb Remove non-functional EFI grub_get_rtc. Put a better fatal message
than current grub_get_rtc() not implemented when booted with
	coreboot without TSC.

	* grub-core/Makefile.am: Exclude efi/time.h from kernel headers.
	Add machine/time.h to kernel headers on loongson.
	* grub-core/Makefile.core.def (kernel): Remove
	kern/generic/rtc_get_time_ms.c on qemu-multiboot-coreboot.
	* grub-core/kern/efi/efi.c (grub_rtc_get_time_ms): Removed.
	(grub_get_rtc): Likewise.
	* grub-core/kern/generic/rtc_get_time_ms.c: Include grub/machine/time.h.
	* grub-core/kern/i386/coreboot/init.c (grub_get_rtc): Removed.
	* grub-core/kern/i386/pc/init.c: Include grub/machine/init.h.
	* grub-core/kern/i386/tsc.c (grub_tsc_init)
	[!GRUB_MACHINE_PCBIOS && !GRUB_MACHINE_IEEE1275]: Call grub_fatal
	rather than installing known non-working time source.
	* grub-core/kern/ieee1275/init.c (grub_get_rtc): Removed.
	* grub-core/kern/mips/loongson/init.c: Include grub/machine/time.h.
	* include/grub/time.h: Don't include machine/time.h.
	* include/grub/efi/time.h: Removed.
	* include/grub/i386/efi/time.h: Likewise.
	* include/grub/i386/ieee1275/time.h: Likewise.
	* include/grub/powerpc/ieee1275/time.h: Likewise.
