Borislav Petkov 26ca123538 x86/ioremap: Fix CONFIG_EFI=n build 
commit 870b4333a6 upstream.

In order to use efi_mem_type(), one needs CONFIG_EFI enabled. Otherwise
that function is undefined. Use IS_ENABLED() to check and avoid the
ifdeffery as the compiler optimizes away the following unreachable code
then.

Fixes: 985e537a40 ("x86/ioremap: Map EFI runtime services data as encrypted for SEV")
