Currently sync_device structure size allocated is nearly 424kb
which is leading to more than accepted page size order.
Sync table row which is array of 2048 is accounting
nearly 90% of total size of sync_device. To fix this
sync_table_row is made pointer based and allocated memory.

Add monitor dump when dma/synx is already in signaled
state or has registered a cb, and when sync fails to
signal its corresponding dma/synx.

Monitor sync object operations such as create, register callback,
signal, unregister callback which is useful in debugging. Introduce
debugfs to dynamically set the monitor mask. Apply dump on error
when CAM_GENERIC_FENCE_TYPE_xx is set in cam_sync_monitor_mask and
apply dump on release when CAM_GENERIC_FENCE_TYPE_xx_DUMP is also set
at the same time. Apply dynamic memory allocation for monitor data
in synx and dma. Refactor APIs into generic ones and add memory
checkings.

Add support to create, release, signal and import a synx object
using the existing generic fence operations. Handle signaling of
underlying synx object when a sync object is signaled & vice versa.

Add support to create, release, signal and import
a dma fence. When a sync object is imported for a dma fence
signal the dma fence when signaling the sync object with
appropriate status. This is achieved by implementing
generic fence scheme. The change also adds support
for batched fences.

For MFHDR plus EIS case, both long and short exposure
input ports will be connected. Thus overall connected
ports for EIS will be 8, resulting in V4L2 queue
depth to 240.

EIS have 6 fences per request and uses 15 frame window. On camera close
it signals ~90 fences at once. This can overflow v4l2 event queue.
Increase v4l2 queue length for sync events to prevent overflow.
