Bay trail DN2820FYKH is supported on Linux but does not work on FreeBSD.

Move ia64 efi.h to sys in preparation for amd64 UEFI support

Prototypes specific to ia64 have been left in this file for now, under
__ia64__, rather than moving them to a new header under sys/ia64.
I anticipate that (some of) the corresponding functions will be shared
by the amd64, arm64, i386, and ia64 architectures, and we can adjust
this as EFI support on other than ia64 continues to develop.

Revert r263321.
vt(9) crash on resume fixed, but Xorg still have damaged screen on resume (at
least with i915kms), so better to switch to VT0 before suspend and back on
resume.

amd64: Parse the EFI memory map if present

With this change (and loader.efi from the projects/uefi branch) we can now
boot under qemu using the OVMF UEFI firmware image with the limitation
that a serial console is required.

(This is largely r246337 from the projects/uefi branch.)
