The OMAP3 ISP IOMMU does not have any reset lines, so it didn't
need any pdata previously. The OMAP IOMMU driver now requires the
platform data ops for device_enable/idle on all the IOMMU devices
after commit db8918f61d51 ("iommu/omap: streamline enable/disable
through runtime pm callbacks") to enable/disable the clocks properly
and maintain the reference count and the omap_hwmod state machine.
So, add these callbacks through iommu pdata quirks for the OMAP3
