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. Cc: Benoit Cousson <b-cousson@ti.com> Signed-off-by: Omar Ramirez Luna <omar.luna@linaro.org> [paul@pwsan.com: fixed some kerneldoc and whitespace; ISP MMUs not present on AM35xx so restricted these hwmods to 34xx/36xx] Signed-off-by: Paul Walmsley <paul@pwsan.com>
