Add implementation to allow forcing all camera buffer allocations
to be CACHED and mapped as CACHED while iommu_map. This
is enabled based on DT property. Force this only if
io-coherency is enabled. Validations are added to make sure
a correct combination of "force_cache" and "io-coherency"
properties are mentioned in DT.

Define debug flag to allocate usecase info for debug purpose.
This flag can be used to get usecase buffer index at issue
time.

Improve debugging infrastructure and logging for memory related
issues. There are scenarios where the fd returned after ion_alloc
exists in camera smmu table as being mapped [stale entry].
On such scenarios, this change will return a specific error code to
userspace. The change also propagates the mapped size back to
user space.

During unmap these internal buffers will be freed immediately
afterwards, therefore there is no need to do cache operation.
