[PATCH v2 1/2] irq: Add EXPORT_SYMBOL_GPL to function of irq generic-chip

[Nobuhiro Iwamatsu]

Some functions of irq generic-chip is undefined, because
EXPORT_SYMBOL_GPL is not set to these.

-----
ERROR: "irq_setup_generic_chip" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_alloc_generic_chip" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_setup_generic_chip" [drivers/gpio/gpio-ml-ioh.ko] undefined!
ERROR: "irq_alloc_generic_chip" [drivers/gpio/gpio-ml-ioh.ko] undefined!
-----

This is revised that EXPORT_SYMBOL_GPL can be added and referred
to in functions.
