soc/intel/skylake: Limit xDCI feature when VBOOT is enabled
Use the common xDCI function to check if the controller is allowed
in the current mode before enabling it. Otherwise, disable the
PCI device if it has been enabled in devicetree.
To make the SOC behavior consistent the XdciEnable config option
is removed in favor of direct control by devicetree.cb and the
mainboards that had defined it were adjusted accordingly.
This was tested on an Eve board with xDCI enabled in devicetree.cb
to ensure the xDCI device is enabled in developer mode and disabled
in normal mode.
