pinctrl: sx150x: Return IRQ_NONE if no pending irq

Browse source

The driver currently reads the interrupt source register, writes the
value back to clear it, and always returns IRQ_HANDLED.
When the IRQ is shared, the handler should not claim interrupts that are
not from this device.

Check for zero interrupt source first. It no interrupt is pending,
return IRQ_NONE and skip the register write.
