imx/gpio: Use handle_level_irq
According to Russell King handle_edge_irq is only useful for "edge-based inputs where the controller does not remember transitions with the input masked." So using handle_edge_irq unconditionally for both edge and level irqs is wrong. Testing showed that the controller does remember transitions while the interrupt is masked. So use handle_level_irq unconditionally.
