soc/intel/common/pcie: Disable removed RPs when updating devicetree 

If a root port is not present but was enabled in the devicetree, mark
it disabled so that no ACPI references will be generated by any
function which walks the devicetree (eg, LPI constraints).

TEST=tested with rest of patch train
