drm/imagination: Set scheduler timeout period higher than Firmware timeout

Browse Source 
Firmware schedules workloads on the GPU and tracks progress.
It is also responsible for detecting any lockup and triggering recovery.

Update the GPU scheduler timeout to a reasonably high value to avoid
premature timeout at the GPU scheduler end.
