When enabling channel measurement fails with a busy condition we wait
for the next interrupt to arrive before we retry the operation. For
devices which usually don't create interrupts we wait forever.

Although the waiting is done interruptible that behavior is not
expected and confused some users. Abort the operation after a 10s
timeout.
