[PATCH 0/6] OMAP: iommu: hwmod, reset handling and runtime PM

Introduced hwmod support for OMAP3 (iva, isp) and OMAP4 (ipu, dsp),
along with the corresponding runtime PM and routines to deassert reset
lines, enable/disable clocks and configure sysc registers.

Due to compatibility an ifdef 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 safely migrated to iommu framework.

Although IOMMU hwmod patches were already submitted in the past,
this series adds few more changes, like:
- New reset handling, based on a series that needs to be accepted first.
- Fix for compile break if IOMMU_API is not selected.
