Currently our UEFI variables are stored in U-Boot variables. Runtime
support for variables is missing. This patch series prepares for
alternative implementations of the variable services.
* QueryVariableInfo() is moved into the same file as the other variable
services.
* For booting via GRUB into Linux UEFI variables are not necessary. An
alternative implementation of the variable services is provided which
only returns EFI_UNSUPPORTED.
* The detaching of runtime services is changed to allow the move to
ExitBootServices().
* The detaching of variable services is moved to ExitBootServices().
* Unimplemented runtime services must return EFI_UNIMPLEMENTED.
* Provide a unit test for variable services at runtime.

efi_loader: initialization of variable services
efi_loader: clean up runtime detaching
efi_loader: let the variable driver patch out the runtime
efi_loader: unimplemented runtime services
efi_selftest: test variable services at runtime
