ARM: orion5x: switch to DT interrupts and timer
This commit switches the Orion5x platforms described through DT to use
a DT-defined interrupt controller and timer.
This involves:
* Describing in the DT the bridge interrupt controller, which is a
child interrupt controller to the main one, which is used for timer
and watchdog interrupts.
* Describing in the DT the timer.
* Adding in the DT the interrupt specifications for the watchdog.
* Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled.
* Change board-dt.c to no longer have an ->init_time() callback,
since the default callback will work fine: it calls
clocksource_of_init() and of_clk_init(), as needed.
* Implement a multi-IRQ handler for non-DT platforms in
mach-orion5x/irq.c.
