Kernel/ScatterGatherList: Add region_name as a part of try_create API

Browse source 
Remove the hardcoded "AHCI Scattered DMA" for region name as it is a
part of a common API. Add region_name parameter to the try_create API
so that this API can be used by other drivers with the correct Memory
region name.
