* soc/intel/common/lpss: Add function to check for a LPSS controllerAamir Bohra2019-08-051-0/+18
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | The initial implementation was assigning the devfn as PCI device reference directly which was incorrect.
