soc/intel/cannonlake: Add required FSP UPD changes for CML

This patch adds required FSP UPD changes for CometLake SoC.
Also this patch tries to create common parse logic for CometLake as
well as cannonlake SOC.

We parse device tree parameters for PCI devices and fill values in FSP
UPDs. We fill UPDs based on pci device config as well as SerialIoDev
config of devicetree.
For PCI devices, if PCI device is disabled from devicetree, we'll assign
disable value to FSP UPD.
In case devicetree doesn't fill this parameter or value is invalid in
SerialIoDev config, default mode will be set to PCI.
In case of valid value, we'll fill the same value into FSP UPD.

BUG=none
BRANCH=none
TEST=check if CML board boots and proper UPD values are filled.
