efi_loader: define internal implementations of install/uninstallmultiple
A following patch is cleaning up the core EFI code trying to remove
sequences of efi_create_handle, efi_add_protocol.
Although this works fine there's a problem with the latter since it is
usually combined with efi_delete_handle() which blindly removes all
protocols on a handle and deletes the handle. We should try to adhere to
the EFI spec which only deletes a handle if the last instance of a protocol
has been removed. Another problem is that efi_delete_handle() never checks
for opened protocols, but the EFI spec defines that the caller is
responsible for ensuring that there are no references to a protocol
interface that is going to be removed.
So let's fix this by replacing all callsites of
efi_create_handle(), efi_add_protocol() , efi_delete_handle() with
Install/UninstallMultipleProtocol.
In order to do that redefine functions that can be used by the U-Boot
proper internally and add '_ext' variants that will be used from the
EFI API
