Use Kernel time to obtain the current time when IFE is acquired
/released and when sensor is streamed on/off. Convert the Ktime
to a timestamp format and log it in existing info prints. This
will help to co-relate timestamp between user-space and kernel
logs. The change also replaces the current usage of direct calls
to ktime_get_real_ts64 with macro across all drivers.

'fd' can be closed in user mode driver, though corresponding
dmabuf is still not freed if someone still holding a refCount
on that dmabuf, say camera smmu driver holding a refCOunt and
has that in its mapping info table. Then the same 'fd' can be
allotted for a different buffer in a new allocation. In such
cases, if we use 'fd' as identifier in camera smmu driver to
check if the buffer is already mapped based on mapping info
table, we mistakenly think the new buffer is already mapped
which is not the case. DMA buf's inode num is an unique
identifier that represents a buffer. Use this along with 'fd'
in camera smmu driver to see if the given buffer is already mapped.

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.

Not calling unmap_hw_va if get_slot() fails causes a stale
entry in smmu CB. since get_slot failed, memmgr table
returns error and memmgr, umd doesn't keep info about this
map entry though smmu CB still has this mapping - This
causes any further map calls on the same 'fd' as smmu
return MAP_EXISTS but CSL bookkeeping doesn't have it.

exists in camera smmu table as being mapped [stale entry].
On such scenarios, this change will return a specific error code to
