[12/16] ARM: spear3xx: use common irqchip_init

Commit Message

Thomas Petazzoni Nov. 20, 2012, 10:01 p.m. UTC

Now that we have a common irqchip infrastructure, use it on the
spear3xx 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.
