Although the OMAP IOMMU driver supports only ARMv7 (32-bit) platforms,
it can be compile tested for other architectures, including 64-bit ones.
In such case the warning appears:
In file included from drivers/iommu/omap-iommu.c:33:0:
drivers/iommu/omap-iommu.c: In function 'omap_iommu_iova_to_phys':
>> drivers/iommu/omap-iopgtable.h:44:21: warning: large integer implicitly truncated to unsigned type [-Woverflow]
#define IOPTE_MASK (~(IOPTE_SIZE - 1))
^
>> drivers/iommu/omap-iommu.c:1641:41: note: in expansion of macro 'IOPTE_MASK'
ret = omap_iommu_translate(*pte, da, IOPTE_MASK);
^~~~~~~~~~
Fix this by using architecture-depending types in omap_iommu_translate():
1. Pointer should be cast to unsigned long,
2. Virtual addresses should be cast to dma_addr_t.
On 32-bit this will be the same as original code (using u32). On 64-bit
it should produce meaningful result, although it does not really matter.

Switch to using the BIT(x) macros in omap-iopgtable.h where
possible. This eliminates the following checkpatch check
warning:
"CHECK: Prefer using the BIT macro"
A couple of macros that used zero bit shifting are defined
directly to avoid the above warning on one of the macros.

Protect the omap-pgtable.h header against double inclusion in
source code by using the standard include guard mechanism.

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
code, most of them are related to broken strings.

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.
