Zbigniew Kempczyński 5572a00468 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.

Now 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.
Passing negative timeout means we will wait "forever" by setting
wait time to MAX_SCHEDULE_TIMEOUT.
