[PATCH 1/2] ledtrig-gpio: Request user input pin as GPIO

The ledtrig-gpio logic assumes the input pin can be directly converted to IRQ using gpio_to_irq. This is problematic since there is no guarantee on the pinmux function nor the direction of the pin. Request the pin as an input GPIO before requesting it as an IRQ. Tested: a free pin can be
