[PATCH v5 2/9] PCI: endpoint: Add missing documentation about the MSI/MSI-X range

[Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx>]

Both pci_epc_raise_irq() and pci_epc_map_msi_irq() APIs expects the
MSI/MSI-X vectors to start from 1 but it is not documented. Add the
range info to the kdoc of the APIs to make it clear.

Fixes: 5e8cb4033807 ("PCI: endpoint: Add EP core layer to enable EP controller and EP functions")
Fixes: 87d5972e476f ("PCI: endpoint: Add pci_epc_ops to map MSI IRQ")
