[PATCH 2/2] misc: atmel_pwm: set initcall level to subsys

Even with the atmel_pwm driver and the atmel-pwm-bl backlight driver
supporting deferred probing, we still want to make sure that any
pwm-device is available when the backlight devices are probed to avoid
any unnecessary delays before enabling the backlight.
