pwm: bcm-iproc: Prevent unloading the driver module while in use
[ Upstream commit 24906a41eecb73d51974ade0847c21e429beec60 ]
The owner member of struct pwm_ops must be set to THIS_MODULE to
increase the reference count of the module such that the module cannot
be removed while its code is in use.
Fixes: daa5abc41c80 ("pwm: Add support for Broadcom iProc PWM controller")
