power: sbs-battery: Request threaded irq and fix dev callback cookie
Currently the battery detect gpio can not be used with a chained interrupt controller that requires threaded irq handlers. Use threaded irq instead. In addition this was not going to be working at present because chip->power_supply is assigned after the request irq call.
