[MIPS] Compile __do_IRQ() when really needed
__do_IRQ() is needed only by irq handlers that can't use
default handlers defined in kernel/irq/chip.c.
For others platforms there's no need to compile this function
since it won't be used. For those platforms this patch defines
GENERIC_HARDIRQS_NO__DO_IRQ symbol which is used exactly for
this purpose.
Futhermore for platforms which do not use __do_IRQ(), end()
method which is part of the 'irq_chip' structure is not used.
This patch simply removes this method in this case.
