The to_iommu definition is used only locally to the omap-iommu.c
source file, and it has nothing to do with the page attributes
defined in omap-iopgtable.h. So, move the definition out of
omap-iopgtable.h header file.

This patch fixes the checkpatch warnings in omap iommu

This file should not be in arch/arm. Move it to drivers/iommu
to allow making most of the header local to drivers/iommu.

This is needed as we are removing plat and mach includes
from drivers for ARM common zImage support.

The iopgtable header file is only used by the iommu & iovmm drivers, so
move it to drivers/iommu/, as part of the single zImage effort.

Prepend 'omap_' to OMAP's 'struct iommu' and exposed API, to prevent
namespace pollution and generally to improve readability of the code
that still uses the driver directly.

Update the users as needed as well.

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).

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.
