i2c: pnx: Fix potential deadlock warning from del_timer_sync() call in isr

Browse source

[ Upstream commit f63b94be69 ]

When del_timer_sync() is called in an interrupt context it throws a warning
because of potential deadlock. The timer is used only to exit from
wait_for_completion() after a timeout so replacing the call with
wait_for_completion_timeout() allows to remove the problematic timer and
its related functions altogether.
