[DistroKit] [PATCH v2] x86_64: kernel: enable EFI support

[Roland Hieber <rhi@pengutronix.de>]

On x86 hardware, EFI is almost always used. Make sure the kernel
supports it, and enable the following config options:

* EFI: EFI runtime service support
* EFI_STUB: Allows a bzImage to be loaded directly by EFI firmware
  without the use of a bootloader
* EFI_RUNTIME_MAP: Export EFI runtime maps to sysfs
* FB_EFI: EFI-based Framebuffer Support
* EFI_HANDOVER_PROTOCOL is selected by default, but also needed to
  support the non-standard handover protocol, which is still used by
  e.g. barebox.

v1 -> v2:
* mention EFI_HANDOVER_PROTOCOL and Reviewed-bys in log message
