soc: qcom: hgsl: Add signaled cb to isync sync

Browse source 
In ts signal mode, usermode maybe create a fences with old timestamp
after timestamp of the timeline goes forward. These fences should be
treated as signaled.
The signaled cb could compare fence ts and timeline ts and return status
to caller.
