soc/intel/common/lpss: Add function to check for a LPSS controller
Add an API to check if device is a LPSS controller. This API can be
used for IRQ assignments for LPSS PCI controllers, since the LPSS
controllers have a requirement of unique IRQ assignments and do not
share same IRQ# with other LPSS controllers.
SOC code is reponsible to provide list of the LPSS controllers
supported and needs to implement soc_lpss_controllers_list API,
in case it needs to use this common implementation.
