soc/intel/skylake: Add integrated LAN config parameters

Add parameters to configure the integrated LAN via FSP.  Since
this takes over a PCI CLKREQ# pin it needs to know which pin
it should use, and there are additional parameters for LTR and
a "K1 power save" feature.

This was tested on a KBL-R board with integrated LAN, verifying
that the device is functional under Linux with the e1000e driver.
