pwm: bcm-iproc: Prevent unloading the driver module while in use

Browse Source 
[ Upstream commit 24906a41ee ]

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: daa5abc41c ("pwm: Add support for Broadcom iProc PWM controller")
