Benjamin Valentin 6ba4225eed tests/periph_pwm: limit OSC_STEPS to 256 to work on all platforms 
The ATmega PWM implementation only supports a maximum resolution of 256.
Thus when running `osci` with `OSC_STEPS` = 1000 an assertion will fail and
the test crashes, even though the PWM peripheral works perfectly fine.

Limit OSC_STEPS to 256 so it works on all platforms.
The LED flashing doesn't look any more coarse.

Expected result

If everything is running as supposed to, you should see a 1KHz PWM with oscillating duty cycle on each channel of the selected PWM device.

Background

Test for the low-level PWM driver.
