[PATCH v3] PCI: mediatek: Configure FC and FTS for functions other than 0

[Ryder Lee]

PCI_FUNC(port->slot << 3)" is always 0, so previously
mtk_pcie_startup_port() only configured FC credits and FTs for
function 0.

Compute "func" correctly so we also configure functions other than
0. This affects MT2701 and MT7623.
