power_supply: Remove IRQF_DISABLED

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts
disabled], We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler returns with
interrupts enabled (see commit [b738a50a: genirq: Warn when handler
enables interrupts]).

So now this flag is a NOOP and can be removed.
