Move OMAP's iommu drivers to the dedicated iommu drivers folder.
While OMAP's iovmm (virtual memory manager) driver does not strictly
belong to the iommu drivers folder, move it there as well, because
it's by no means OMAP-specific (in concept. technically it is still
coupled with OMAP's iommu).
Eventually, iovmm will be completely replaced with the generic,
iommu-based, dma-mapping API.

Migrate OMAP's iommu driver to the generic IOMMU API, so users can stay
generic, and any generic IOMMU functionality can be developed once
in the generic framework.
Migrate omap's iovmm (virtual memory manager) to the generic IOMMU API,
and adapt omap3isp as needed, so the latter won't break.
The plan is to eventually remove iovmm completely by replacing it
with the (upcoming) IOMMU-based DMA-API.
Tested on OMAP3 (with omap3isp) and OMAP4 (with rpmsg/remoteproc).

A bit more strict comparison.

This is just a cleanup, but adds a few macros here, which can be used
in the proceeding patches.

This patch provides:
- iotlb_*() : iommu tlb operations
- iopgtable_*() : iommu pagetable(twl) operations
- iommu_*() : the other generic operations
and the entry points to register and acquire iommu object.
