ide: use PIO/MMIO operations directly where possible (v2)
This results in smaller/faster/simpler code and allows future optimizations. Also remove no longer needed ide[_mm]_{inl,outl}() and ide_hwif_t.{INL,OUTL}. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
