Hmm... thanks.
But I can't really pull this through the LED tree as it touches other
people's code.

You can delete this.
Probably new type should be called led_brightness_t. And probably it
should be typedef for the enum _for now_, so that we can switch users
gradually.
It should also be more than u8, I believe someone has more than 255
levels at this point.
