power: supply: ab8500_charger: Oneshot threaded IRQs

Make sure the threaded IRQs requested by the charger are
flagged as "oneshot". Usually this is what you want, and
since the interrupts are shared with the USB phy on the
AB8500 we will get a conflict like this if we don't,
since the phy request them threaded oneshot:

genirq: Flags mismatch irq 83. 00004084 (USB_LINK_STATUS
  vs. 00006084 (usb-link-status)
ab8500-charger ab8500-charger.0: failed to request
  USB_LINK_STATUS IRQ 83: -16
