backlight: atmel-pwm-bl: remove unnecessary platform_set_drvdata()

Browse Source 
The driver core clears the driver data to NULL after device_release or
on probe failure, since commit 0998d06310 ("device-core: Ensure drvdata
= NULL when no driver is bound").

Thus, it is not needed to manually clear the device driver data to NULL.
