[PATCH 4/7] arm: efi: add a generic efi machine.

[chalianis1@gmail.com]

From: Chali Anis <chalianis1@gmail.com>

add a generic arm64 machine that can select the CPU_V8 and the
required efi payload minimal configs. this machine permits to have
a clean arm64 efi payload, idealy we don't need the other machine
that comes from multi arch since they execute code that is specific
for the correspondig hardware. with this generic efi machine the
barebox log shell is more clean. to get a pure clean efi payload
you need to unselect all the other arch machines and keep only the
EFI ARM64.
