intel/aux_map: Rename some variables to improve readability

Browse Source 
No changes in behavior here, mostly doing this types of renames:
- address to main_address, to know that addresses refers to main
surface address or aux surface address
- gpu to addr
- main_map_addr to main_inc_addr
- aux_dest_addr to aux_inc_addr
