[PATCH for-4.4 5/7] MIPS: Select HAVE_IRQ_EXIT_ON_IRQ_STACK

[Amit Pundir]

From: Matt Redfearn <matt.redfearn@xxxxxxxxxx>

Since do_IRQ is now invoked on a separate IRQ stack, we select
HAVE_IRQ_EXIT_ON_IRQ_STACK so that softirq's may be invoked directly
from irq_exit(), rather than requiring do_softirq_own_stack.
