These 2 patches provide a means to eliminate plat_irq_dispatch() on platforms that can do without it. Patch #1 adds a new config symbol which, when set, calls a generic MIPS irq dispatcher. All interrupts controllers hanging off these interrupts must be registered as chain handlers. Patch #2 implements the above on Alchemy. Tested on various DB1xxx boards, with and without the C0 timer. Finally, all credits should go to Ralf as he suggested the idea to me.
