mb/siemens/mc_ehl1: Clean up PCIe root port settings in devicetree
PCIe root ports #5 (00:1c.4) and #6 (00:1c.5) are not used on this
mainboard and are not routed either, so remove them from the devicetree
completely. PCIe root port #7 (00:1c.6) is connected and used. Add the
missing settings for L1 substates and latency reporting to disable these
features for this port as well.
