intel/minnowmax: Enable all PCIe ports
A recently announced Turbot system populates two Ethernet
controllers. Enable the remaining disabled PCIe port.
Also add a clarifying comment regarding the port associated
with Function 0. Coreboot must not be allowed to disable the
function which breaks PCI compatibility.
