backlight: atmel-pwm-bl: fix deferred probe from __init
commit 9d3fde86b15303decea632c929fbf1f3ae4501f2 upstream. Move probe out of __init section and don't use platform_driver_probe which cannot be used with deferred probing. Since commit e9354576 ("gpiolib: Defer failed gpio requests by default") this driver might return -EPROBE_DEFER if a gpio_request fails.
