Repurpose the existing EFI earlyprintk code to implement support for
'earlycon=efi' for arm64 systems, allowing the graphical console
to be used instead of the serial port for early debug output.

efi: x86: move EFI earlyprintk code to shared location
efi: arm64: Enable earl
Move the x86 EFI earlyprintk to a shared location under drivers/firmware
and tweak it slightly so we can easily reuse it for other architectures
going forward.

This repurposes the existing EFI earlyprintk support and exposes it
as an earlycon implementation, which can be enabled by passing the
kernel parameter 'earlycon=efi' on the command line.
Note that the early console is initialized before we have discovered
anything about the memory map, and so we
For a while Arm64 has been capable of force enabling
or disabling the kpti mitigations. Lets make sure the
documentation reflects that.

There are various reasons, including bencmarking, to disable spectrev2
mitigation on a machine. Provide a command-line to do so.
