sh: fix INTC to use set_irq_chained_handler() for redirects
This patch updates the shared INTC code to use
set_irq_chained_handler() for intc_redirect_irq().
With this in place request_irq() on a merged irq
which has been redirected will now return -EINVAL
instead of 0 together with a crash. This thanks to
the protection of the IRQ_NOREQUEST flag set for
chained interrupt handlers.
