Input: synaptics-rmi4 - convert irq distribution to irq_domain
Convert the RMI driver to use the standard mechanism for distributing IRQs to the various functions. Tested on: * S7300 (F11, F34, F54) * S7817 (F12, F34, F54) Signed-off-by: Nick Dyer <nick@shmanahar.org> Acked-by: Christopher Heiny <cheiny@synaptics.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
