hw/isa/vt82c686: Add missing Kconfig dependency (runtime error)

When building the Pegasos2 machine stand-alone we get:

  $ qemu-system-ppc -M pegasos2 -bios pegasos2.rom
  ERROR:qom/object.c:714:object_new_with_type: assertion failed: (type != NULL)
  Bail out! ERROR:qom/object.c:714:object_new_with_type: assertion failed: (type != NULL)

Looking at the backtraces:

  Thread 1 "qemu-system-ppc" received signal SIGABRT, Aborted.

The "isa-pit" type (TYPE_I8254) and "isa-parallel" are missing. Add them.
