ARM: OMAP3: hwmod data: add mmu data for iva and isp
Add mmu hwmod data for iva and isp.
Due to compatibility an ifdef CONFIG_OMAP_IOMMU_IVA2 needs to be
propagated (previously on iommu resource info) to hwmod data in OMAP3,
so users of iommu and tidspbridge can avoid issues of two modules
managing mmu data/irqs/resets; this until tidspbridge can be migrated
to iommu framework.

[paul@pwsan.com: fixed some kerneldoc and whitespace; ISP MMUs not present
on AM35xx so restricted these hwmods to 34xx/36xx]
