ARM: OMAP2+: Add pdata for OMAP3 ISP IOMMU

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
ISP IOMMU.
