    drm/xe: Use nanoseconds instead of jiffies in uapi for user fence
    
    Using jiffies as a timeout from userspace is weird even if
    theoretically exists possiblity of acquiring jiffies via getconf.
    Unfortunately this method is unreliable and the returned
    value may vary from the one configured in the kernel config.
    
    From now on timeout is expressed in nanoseconds and its interpretation
    depends on setting DRM_XE_UFENCE_WAIT_ABSTIME flag. Relative timeout
    (flag is not set) means fence expire at now() + timeout. Absolute
    timeout (flag is set) means that the fence expires at exact point
    of time.
