Johan Hovold 09675c2f84 gnss: sirf: fix premature wakeup interrupt enable ...

commit 82f844c225 upstream.

Make sure the receiver is powered (and booted) before enabling the
wakeup interrupt to avoid spurious interrupts due to a floating input.

Similarly, disable the interrupt before powering off on probe errors and
on unbind.
