Laurent Pinchart e8a6ebc71e iommu/omap: Remove platform data da_start and da_end fields
The fields were used by the now gone omap-iovmm driver. They're not used
anymore, remove them.

Omar Ramirez Luna ebf7cda0f9 iommu/omap: Adapt to runtime pm
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.

Omar Ramirez Luna 72b15b6ae9 iommu/omap: Migrate to hwmod framework
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.
