soc/intel: Drop unused lpss functions

This change drops the following unused lpss functions and related
code:
* soc_lpss_controllers_list
* is_dev_lpss

These functions were added to determine if a controller is LPSS for
performing IRQ configuration. But, these never got used and hence are
being dropped.
