soc/intel/common: Add function to check if xDCI is allowed
When CONFIG_VBOOT is enabled then the xDCI controller should only be
enabled if the system is in developer mode. This prevents a system
in normal/verified mode from being used as a USB peripheral device
which could potentially be used to access user data.
This change adds a function to return whether xDCI can be enabled
or not, which will be used by the SOCs.
