pwm: omap-dmtimer: Remove PWM chip in .remove before making it unfunctional
[ Upstream commit 43efdc8f0e6d7088ec61bd55a73bf853f002d043 ]
In the old code (e.g.) mutex_destroy() was called before
pwmchip_remove(). Between these two calls it is possible that a PWM
callback is used which tries to grab the mutex.
