clock: introduce non interruptible timeout
...
is_timeout call poller_call if the timeout is >= 100us
but on 1-wire bus we need to wait 500us and not more than 930us
for the bus reset. So if the poller_call is caller we can not guarantee it.
So for this introduce is_non_interruptible_timeout than we only wait.
Use it for ndelay too.
