[PATCH] pwm: sl28cpld: Set driver data before registering the PWM chip

[Thierry Reding <thierry.reding@gmail.com>]

The PWM core code can call back into the PWM chip's implementation at
any time after the chip has been registered. Since the driver uses
driver data to store contextual information, registration must happen
after the driver data has been set.
