pwm: bcm2835: Fix NPD in suspend/resume

When 119a508 ("pwm: bcm2835: Add support for suspend/resume") was sent out on October 11th,, there was still a call to platform_set_drvdata() which would ensure that the driver private data structure could be used in bcm2835_pwm_{suspend,resume}. A cleanup now merged as commit commit 2ce7b7f ("pwm: bcm2835: Simplify using devm functions") removed that call which would now cause a NPD in bcm2835_pwm_{suspend,resume} as a consequence.
