[PATCH 11/16] ARM: picoxcell: use common irqchip_init

[Thomas Petazzoni]

Now that we have a common irqchip infrastructure, use it on the
picoxcell platform:

 * Use irqchip_init() as the ->irq_init() machine function. The
   irqchip infrastructure already knows about the compatible strings
   for the VIC IRQ controller driver.

 * No longer needed to set ->handle_irq() in the machine structure, as
   it will be set by the VIC IRQ controller driver.
