power: supply: ab8500_fg: Request all IRQs as threaded
Since these IRQs are cascaded from a nested IRQ, the
generic IRQ system detects this and refuse to deliver
a fastpath IRQ in response to request_irq():
nested = irq_settings_is_nested_thread(desc);
if (nested) {
if (!new->thread_fn) {
ret = -EINVAL;
goto out_mput;
}
(...)
Threaded IRQs work just as well so let's just request
threaded IRQs. One of the IRQs are alread requested
as threaded anyways.
