x86: isolate PIC/PIT in/out calls

Rather than remove and/or mangle inb_p/outb_p we want to remove the use
of them from inappropriate places. For the PIC/PIT this may eventually
depend on 32/64bitism or similar so start by adding inb/outb_pit and
inb/outb_pic so that we can make them use any scheme we settle on without
disturbing the existing, correct (for ISA), port 0x80 usage. (eg we can
make inb_pit use udelay without messing up inb_p).

Floppy already does this for the fdc. That really only leaves the CMOS as
a core logic item to tackle, and bits of parallel port handling in the
chipset layers.
