PCI: Remove pci_get_legacy_ide_irq() and asm-generic/pci.h 

pci_get_legacy_ide_irq() is only used on platforms that support PNP, so
many architectures define it but never use it.  Replace uses of it with
ATA_PRIMARY_IRQ() and ATA_SECONDARY_IRQ(), which provide the same
functionality.

Since pci_get_legacy_ide_irq() is no longer used, remove all the
architecture-specific definitions of it as well as asm-generic/pci.h, which
only provides pci_get_legacy_ide_irq()
