Change {cdns, dra7xx, artpec6, dw, rockchip}_pcie_ep_raise_irq() and
pci_epc_raise_irq() signature, namely the interrupt_num variable type
from u8 to u16 to accommodate 2048 maximum MSI-X interrupts.

Change v1->v2:
 - Nothing changed, just to follow the patch set version.
Change v2->v3:
 - Move into here the pci_epc_raise_irq() signature change from patch
file #1.
 - Move into here the {dra7xx, artpec6}_pcie_ep_raise_irq() signature
changes from patch file #2.
Change v3->v4:
 - Rebased to Lorenzo's master branch v4.18-rc1.
Change v4->v5:
 - Swap patch files position (#3 -> #2).
 - Moved dw_pcie_ep_raise_irq and dw_plat_pcie_ep_raise_irq functions
signatures changes from patch file #3.
 - Changed rockchip_pcie_ep_raise_irq function signature.
Change v5->v6:
 - Nothing changed, just to follow the patch set version.
Change v6->v7:
 - Nothing changed, just to follow the patch set version.
Change v7->v8:
 - Re-sending the patch series.
