For X540 onwards it is possible if a system reset occurs at the right time to leave the SWFW semaphore high. This new function will attempt to grab and release the semaphore. If the grab times out it will still release the semaphore placing it in a known good state. The idea is to call this when you know no one should be holding the semaphore (i.e. probe time) Signed-off-by: Beilei Xing <beilei.xing@intel.com>
