ARM: OMAP2+: add pdata-quirks for OMAP3 ISP IOMMU

The OMAP3 ISP IOMMU does not have any reset lines, so it didn't
need any pdata. The OMAP IOMMU driver now requires the platform
data ops for device_enable/idle on all the IOMMU devices to be
able to enable/disable the clocks and maintain the reference
count and the omap_hwmod state machine. So, add the iommu pdata
quirks for the OMAP3 ISP IOMMU.
