drivers/misc/sgi-xp: clean up return values
Make XP return values more generic to XP and not so tied to XPC by changing enum xpc_retval to xp_retval, along with changing return value prefixes from xpc to xp. Also, cleanup a comment block that referenced some of these return values as well as the handling of BTE related return values.
