zephyr: shim: implement a default led_set_brightness
Implement a default led_set_brightness, should be good enough to replace
all existing pwm leds currently defined:
atlas, nocturne: 2 leds with independent channels
volteer, boldar, trondo: 2 leds with sidesel
terrador, todor, waddledee, wheelie: 1 led
brya, kano, liara, waddledoo: 2 leds but only amber/white
grunt:1 led with only blue/amber
BRANCH=none
BUG=b:177452529
TEST=build and run on volteer
TEST=gdb disassemble/s led_set_brightness
