backports: Fix pci_alloc_irq_vectors() backport

This copies the pci_alloc_irq_vectors() function from kernel 4.9 and
replaces the __pci_enable_msi{x}_range() calls with calls to
pci_enable_msi{x}_range(), these were backported to kernel versions <
3.14, so no need to handle the older kernels specially here.

This also adds support for MSIx IRQs and adds the PCI_IRQ_* defines.

Fixes: 162a6b312f1b ("add support for pci_alloc_irq_vectors")
