hw/intc: GICv3 ITS Command processing
Added ITS command queue handling for MAPTI,MAPI commands,handled ITS translation which triggers an LPI via INT command as well as write to GITS_TRANSLATER register,defined enum to differentiate between ITS command interrupt trigger and GITS_TRANSLATER based interrupt trigger. Each of these commands make use of other functionalities implemented to get device table entry,collection table entry or interrupt translation table entry required for their processing.
