firmware: raspberrypi: Introduce rpi_firmware_find_node()
A significant number of RaspberryPi drivers using the firmware don't
have a phandle to it, so end up scanning the device tree to find a node
with the firmware compatible.
That code is duplicated everywhere, so let's introduce a helper instead.
