PCI: Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX

Browse source 
[ Upstream commit 58ff9c5acb4aef58e118bbf39736cc4d6c11a3d3 ]

Rename PCI_IRQ_LEGACY to PCI_IRQ_INTX to be more explicit about the type
of IRQ being referenced as well as to match the PCI specifications
terms. Redefine PCI_IRQ_LEGACY as an alias to PCI_IRQ_INTX to avoid the
need for doing the renaming tree-wide. New drivers and new code should
now prefer using PCI_IRQ_INTX instead of PCI_IRQ_LEGACY.
