This patch attempts to modernize core Alchemy interrupt handling code. - add irq_chips for irq controllers instead of irq type, - add a set_type() hook to change irq trigger type during runtime, - add a set_wake() hook to control GPIO0..7 based wakeup, - use linux' IRQF_TRIGGER_ constants instead of homebrew ones, - enable GENERIC_HARDIRQS_NO__DO_IRQ. - simplify plat_irq_dispatch - merge au1xxx_irqmap into irq.c file, the only place where its contents are referenced. - board_init_irq() is now mandatory for every board; use it to register the remaining (gpio-based) interrupt sources; update all boards accordingly. Run-tested on Db1200 and other Au1200 based platforms.
