PCI: dwc: ep: Fix MSI-X Table Size configuration in dw_pcie_ep_set_msix()
In dw_pcie_ep_set_msix(), while updating the MSI-X Table Size value for
individual functions, Message Control register is read from the passed
function number register space using dw_pcie_ep_readw_dbi(), but always
written back to the Function 0's register space using dw_pcie_writew_dbi().
This causes incorrect MSI-X configuration for the rest of the functions,
other than Function 0.
Fix this by using dw_pcie_ep_writew_dbi() to write to the correct
function's register space, matching the read operation.
Fixes: 70fa02ca1446 ("PCI: dwc: Add dw_pcie_ep_{read,write}_dbi[2] helpers")
