[PATCH v3 01/11] accel/ivpu: Move set autosuspend delay to HW specific code

[Stanislaw Gruszka]

From: Krystian Pradzynski <krystian.pradzynski at linux.intel.com>

Configure autosuspend values per HW generation and per platform.

For non silicon platforms disable autosuspend for now, for silicon
reduce it to 10 ms.
