target/ppc: Remove last user of .load_state_old 

This breaks migration compatibility from (very) old versions of
QEMU. This should not be a problem for the pseries machine for which
migration is only supported on recent QEMUs ( > 2.x). There is no
clear status on what is supported or not for the other machines. Let's
move forward and remove the .load_state_old handler.
