Root Ports can generate several different interrupts using either MSI or MSI-X, but we only support that for MSI-X. Ports that support MSI but not MSI-X are currently limited to sharing a single interrupt. Rename pcie_port_enable_msix() to pcie_port_enable_irq_vec() and extend it to support multiple interrupts using either MSI-X (preferred) or MSI.
