- sharing most UEFI code, will replace the `virtual` one soon
- x86: patch uboot defconfig to use the `q35` machine type, not `i440fx`
- separate x86 bootscript, due to non-uInitrd-ness of it
- hack ramdisk load address both in u-boot source and bootscript
- use 32-bit u-boot, not 64-bit
- grub: introduce `UEFI_GRUB=skip`, does not deploy GRUB (but does the kernel packages, etc)
- auto-enable qcow2 output for these
- works with both distro's and Armbian's kernels
