ARM: orion: simplify orion_ge00_switch_init
One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.
However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.
Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.
