The recently added Emma Mobile GPIO driver calls set_irq_flags
and irq_set_chip_and_handler for the interrupts it exports and
it can be built as a module, which currently fails with

ERROR: "set_irq_flags" [drivers/gpio/gpio-em.ko] undefined!
ERROR: "irq_set_chip_and_handler_name" [drivers/gpio/gpio-em.ko] undefined!

We either need to replace the call to set_irq_flags with something
else or export that function. This patch does the latter.
