sonypi: try to detect if sony-laptop has already taken one of the known ioports
Get the IO resources list in sony-laptop in the same order as listed
in sonypi and make sonypi check if one of those is already busy.
The sonypi check can be disabled by a module parameter in case the user
thinks we are plainly wrong (check_ioport=0).
