[MIPS] IRQ cleanups
This is a big irq cleanup patch.
* Use set_irq_chip() to register irq_chip.
* Initialize .mask, .unmask, .mask_ack field. Functions for these
method are already exist in most case.
* Do not initialize .startup, .shutdown, .enable, .disable fields if
default routines provided by irq_chip_set_defaults() were suitable.
* Remove redundant irq_desc initializations.
* Remove unnecessary local_irq_save/local_irq_restore, spin_lock.
With this cleanup, it would be easy to switch to slightly lightwait
irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ().
Though whole this patch is quite large, changes in each irq_chip are
not quite simple. Please review and test on your platform. Thanks.
