alpha: Replace setup_irq() by request_irq()
request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
setup_irq() was required in older kernels as the memory allocator was not
available during early boot.
Hence replace setup_irq() by request_irq().
