unicore32: pwm: Use module_platform_driver()
Some of the boilerplate code can be eliminated by using this macro. The driver was previously registered with an arch_initcall(), so technically this is no longer the same, but when the driver is moved to the PWM framework, deferred probing will take care of any driver probe ordering issues.
