dw_pcie_ep_raise_msix_irq was never called in the exisitng driver
before, because the ls1046a platform don't support the MSIX feature
and msix_capable was always set to false.
Now that add the ls1088a platform with MSIX support, but the existing
dw_pcie_ep_raise_msix_irq doesn't work, so use the doorbell method to
support the MSIX feature.
