[PATCH 4.4 127/342] irqchip/mxs: Add missing set_handle_irq()

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Oleksij Rempel <linux@xxxxxxxxxxxxxxxx>

commit c5b635203032462603c503ecce91a7021c1ad44a upstream.

The rework of the driver missed to move the call to set_handle_irq() into
asm9260_of_init(). As a consequence no interrupt entry point is installed and
no interrupts are delivered

Solution is simple: Install the interrupt entry handler.

Fixes: 7e4ac676ee ("irqchip/mxs: Add Alphascale ASM9260 support")
