Add support of the option to pass a 64-bit client_data value to
the hw fence driver when a client registers as a waiting client
for a hardware fence. Then during fence signaling, this client_data
is returned to the client via the RxQ.
If no client_data is passed to the driver for the hw fence, then a
default value of zero is registered as the client_data.

Current driver creates a join hw-fence from a fence-array, adds its
waiting client to it, and then it decides if signal the hw-fence
depending in the current state of all the child hw-fences from the
fence array.
However, if by any reason the fence-array gets all its children cleared
within it (which can happen for spec-fences failures), hw-fence driver
logic won't signal the new created join-fence.
This can lead to the creation of an empty or incomplete join-fence that
the waiting-client will be waiting-for, but won't be signaled.
Add a check to make sure that if above scenario is ever presented,
the register for wait API catches this issue and fails to register
for wait in this invalid fence.

It is possible that one (or more) child fences get signaled by
fence controller, right after we add the join fence as parent
fence of the child fence. If so, the join fence pending child
count may become 0 which means we can safely signal the join
fence.

Also, set update_rxq property for GPU client to false, as GPU doesn't need
