bsps/amd64: add a new EFI-based variant of AMD64 BSP
The new amd64efi BSP supports:
- multiboot2 boot format. Runs well with GRUB.
- console based on either EFI simple text output or GOP-based framebuffer
- clock based on EFI event/timer API
- early console using either hard-wired PC-AT serial or just memory buffer
- with EFI support disabled the BSP is more or less equivalent to amd64 BSP
with multiboot2 support
