sparc64: Rewrite central driver.
This driver is now limited to just doing the basic clock board and FHC chip initialization and registering the platform devices for the per-board LEDs, which are driven by the new LEDS_STARFIRE driver. The IRQ register handling is already confined purely to the device tree code. Signed-off-by: David S. Miller <davem@davemloft.net>
