hw/i386: Remove obsolete LoadStateHandler::load_state_old handlers

These devices implemented their load_state_old() handler 10 years
ago, previous to QEMU v0.12.
Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines,
we can drop this code.

Note: the mips_r4k machine started to use the i8254 device just
after QEMU v0.5.0, but the MIPS machine types are not versioned,
so there is no migration compatibility issue removing this handler.
