These functions are the enable/disable for module-level wakeups, you need to use the proposed enable/disable functions for IO ring wakeups as proposed in the patch from Govindraj[1]. I'm hoping that patch will be queued for v3.1, but will wait for Paul's comments on that patch.

PRCM chain interrupt registration is done now as part of omap_hwmod_enable_wakeup() and omap_hwmod_disable_wakeup() calls. This allows module ISR:s to be called when the module is idle but an IO_PAD event is detected on the module input pads.
