irqchip/sirfsoc: Fix generic chip allocation wreckage
irq_alloc_domain_generic_chips() can only be called once for an irqdomain. The sirfsoc init calls it twice and because the return value is not checked it does not notice the wreckage. The code works by chance because the first call already allocates two chips and therefor the second call to sirfsoc_alloc_gc() operates on the proper generic chip instance. Use a single call and setup the two chips in the obvious correct way.
