The internal data-structures are scattered over various
header and C files. Consolidate them in omap-iommu.h.
While at this, add the kerneldoc comment for the missing
iommu domain variable and revise the iommu_arch_data name.

All the supported boards that have OMAP IOMMU devices do support
DT boot only now. So, drop the support for the non-DT legacy-style
devices from the OMAP IOMMU driver. Couple of the fields from the
iommu platform data would no longer be required, so they have also
been cleaned up. The IOMMU platform data is still needed though for
performing reset management properly in a multi-arch environment.

The structure omap_mmu_dev_attr was used in the hwmod data for
supplying device-specific data through the .dev_attr field and
used in constructing the platform data for legacy device creation.
The legacy device creation of OMAP IOMMU devices has been cleaned
up, and this structure is no longer needed, so remove it.

The fields were used by the now gone omap-iovmm driver. They're not used
anymore, remove them.

Use runtime PM functionality interfaced with hwmod enable/idle
functions, to replace direct clock operations and sysconfig
handling.
Due to reset sequence, pm_runtime_[get|put]_sync must be used, to
avoid possible operations with the module under reset. Because of
this and given that the driver uses spin_locks to protect their
critical sections, we must use pm_runtime_irq_safe in order for the
runtime ops to be happy, otherwise might_sleep_if checks in runtime
framework will complain.
The remaining pm_runtime out of iommu_enable and iommu_disable
corresponds to paths that can be accessed through debugfs, some of
them doesn't work if the module is not enabled first, but in future
if the mmu is idled withouth freeing, these are needed to debug.

Use hwmod data and device attributes to build and register an
omap device for iommu driver.
- Update the naming convention in isp module.
- Remove unneeded check for number of resources, as this is now
handled by omap_device and prevents driver from loading.
- Now unused, remove platform device and resource data, handling
of sysconfig register for softreset purposes, use default
latency structure.
- Use hwmod API for reset handling.

Move iommu/iovmm headers from plat/ to platform_data/ as part of the
single zImage work.
Partially based on an earlier version by Ido Yariv <ido@wizery.com>.
