[PATCH v2 37/38] ARM: orion: remove no longer needed DT IRQ code

[Thomas Petazzoni]

Following the move of the Orion5x Device Tree support to use
irqchip_init() for the interrupt controller probing, the
plat-orion/irq.c code for DT-probing of the interrupt controller is no
longer necessary, so we can get rid of it.
