disp: msm: sde: increase display kickoff timeout for hw-fences

Starting with HW-Fencing, the frames hw kickoff
can take longer to trigger, given that HW will wait for the
input fences signal. Therefore, this change increments
the time-outs to wait up to ~10 secs, which corresponds
to the current input dma-fences timeout. This ~10secs
wait is given in intervals, where the dma-fence is also
checked, so in case that the client producer of the fence
signals the dma-fence, but misses the hw-fence signaling,
Display driver can handle this case and do a sw-override
to start the fetching of the incoming frame without waiting
for the input hw-fence ipc signal.
