eeti touch screen controller is an external chip for most platforms,
it connect to CPU via i2c bus, and it has a irq request pin need to be
connected to a gpio of the CPU, this irq request pin also act as a
wake up signal for touch screen controller, we need to get this gpio
number and operate it to wake up the controller, the old way to get
gpio is irq_to_gpio(), this API is dying and most platforms don't support
it, we change it to a more generic way to use devcietree.
