efi: x86: Move EFI runtime map sysfs code to arch/x86
The EFI runtime map code is only wired up on x86, which is the only
architecture that has a need for it in its implementation of kexec.
So let's move this code under arch/x86 and drop all references to it
from generic code. To ensure that the efi_runtime_map_init() is invoked
at the appropriate time use a 'sync' subsys_initcall() that will be
called right after the EFI initcall made from generic code where the
original invocation of efi_runtime_map_init() resided.
