Majority of host drivers using IDE PCI layer set drive->autotune, the only
exceptions are:
generic.c
ns87415.c
rz1000.c
trm290.c
* no ->set_pio_mode method
it821x.c:
* if memory allocation fails drive->autotune won't be set
(but there also won't be ->set_pio_mode method in such case)
piix.c:
* MPIIX controller (no ->init_hwif method so also no ->set_pio_mode method)
However if there is no ->set_pio_mode method there are no changes in behavior
w.r.t. PIO tuning so always set drive->autotune in ide_pci_setup_ports().

Since cs5520 uses VDMA best PIO mode was tuned anyway by ide_dma_check()
but only if DMA was successfully initialized.

Add IDE_HFLAG_LEGACY_IRQS host flag to tell ide_pci_setup_ports() to set
hwif->irq to legacy IRQ 14/15 (iff hwif->irq is not already set) and convert
atiixp, piix, serverworks, sis5513 and slc90e66 host drivers to use it.
While at it:
* In piix.c add IDE_HFLAGS_PIIX define and don't use ->init_hwif for MPIIX.
