PCI: dwc: endpoint: Fix dw_pcie_ep_raise_msix_irq() alignment support

Commit 6f5e193bfb55 ("PCI: dwc: Fix dw_pcie_ep_raise_msix_irq() to get
correct MSI-X table address") modified dw_pcie_ep_raise_msix_irq() to
support iATUs which require a specific alignment.

However, this support cannot have been properly tested.

The whole point is for the iATU to map an address that is aligned,
using dw_pcie_ep_map_addr(), and then let the writel() write to
ep->msi_mem + aligned_offset.

Thus, modify the address that is mapped such that it is aligned.
With this change, dw_pcie_ep_raise_msix_irq() matches the logic in
dw_pcie_ep_raise_msi_irq().
