genirq: generic-chip: Export some irq_gc_ functions 

When building imx_v6_v7_defconfig with imx-drm drivers selected as
modules, we get the following build errors:

ERROR: "irq_gc_mask_clr_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!
ERROR: "irq_gc_mask_set_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!
ERROR: "irq_gc_ack_set_bit" [drivers/staging/imx-drm/ipu-v3/imx-ipu-v3.ko] undefined!

Export the required functions to avoid this problem.
