[PATCH v2] pwm: atmel: Remove platform_device_id and use only dt bindings

[Kamel Bouhara]

Since commit 26202873bb51 ("avr32: remove support for AVR32
architecture") there is no more user of platform_device_id and we
should only use dt bindings

Changelog:
 v1->v2
 
 - Remove whole function atmel_pwm_get_driver_data and call
 of_device_get_match_data from atmel_pwm_probe
