The definition of the pci header function pci_get_legacy_ide_irq is only
used in platforms that support PNP. So many of the architecutres where
it is defined do not use it. This also means we can remove
asm-generic/pci.h as all it provides is a definition of
pci_get_legacy_ide_irq.
Where referenced, replace the usage of pci_get_legacy_ide_irq with the
libata.h macros ATA_PRIMARY_IRQ and ATA_SECONDARY_IRQ which provide the
same functionality. This allows removing pci_get_legacy_ide_irq from
headers where it is no longer used.
