irqdomain: Mask irq type in irq_domain_xlate_onetwocell()
According to the xlate() callback definition, the 'out_type' parameter needs to be the "linux irq type". A mask for such bits exists, IRQ_TYPE_SENSE_MASK, which is correctly applied in irq_domain_xlate_twocell() So use it for irq_domain_xlate_onetwocell() as well.
