[Intel-gfx] [PATCH v5 i-g-t 14/15] tests/i915/i915_hangman: Configure engine properties for quicker hangs

[John . C . Harrison]

From: John Harrison <john.c.harri...@intel.com>

Some platforms have very long timeouts configured for some engines.
Some have them disabled completely. That makes for a very slow (or
broken) hangman test. So explicitly configure the engines to have
reasonable settings first.
