pwm: twl: Really disable twl6030 PWMs
...
Current twl6030_pwm_disable() implementation writes TWL6030_TOGGLE3_REG
twice, the second write sets TWL6030_PWMXEN bits so the PWM clock does
not disable.

A few drivers already annotate this properly. Make the same change for
all other OF supporting drivers.

pwm: twl: Add .owner to struct pwm_ops
...
Add missing .owner of struct pwm_ops. This prevents the module from being
removed from underneath its users.

pwm: New driver to support PWMs on TWL4030/6030 series of PMICs
...
The driver supports the following PWM outputs:
TWL4030 PWM0 and PWM1
TWL6030 PWM1 and PWM2
On TWL4030 the PWM signals are muxed. Upon requesting the PWM the driver
will select the correct mux so the PWM can be used. When the PWM has been
freed the original configuration is going to be restored.
