samples: drivers: add test sample for the PWM LED driver
This sample allows to test the led-pwm driver. The first "pwm-leds"
compatible device instance found in DT is used. For each LEDs attached
to this device (child nodes) the same test pattern (described below) is
executed. The LED API functions are used to control the LEDs.
Test pattern:
For each PWM LEDs (one after the other):
- turn on
- turn off
- increase the brightness gradually up to the maximum level
- blink (0.1 sec on, 0.1 sec off)
- blink (1 sec on, 1 sec off)
- turn off
