chromeos: Simplify fill_lb_gpios even further

A long time ago many Chrome OS boards had pages full of duplicated
    boilerplate code for the fill_lb_gpios() function, and we spent a lot of
    time bikeshedding a proper solution that passes a table of lb_gpio
    structs which can be concisely written with a static struct initializer
    in http://crosreview.com/234648. Unfortunately we never really finished
    that patch and in the mean time a different solution using the
    fill_lb_gpio() helper got standardized onto most boards.

Still, that solution is not quite as clean and concise as the one we had
    already designed, and it also wasn't applied consistently to all recent
    boards (causing more boards with bad code to get added afterwards). This
    patch switches all boards newer than Link to the better solution and
    also adds some nicer debug output for the GPIOs while I'm there.

If more boards need to be converted from fill_lb_gpio() to this model
    later (e.g. from a branch), it's quite easy to do with:
    s/fill_lb_gpio(gpio++,\n?\s*([^,]*),\n?\s*([^,]*),\n?\s*([^,]*),\n?\s*([^,]*));/\t{\1, \2, \4, \3},/

Based on a patch by Furquan Shaikh .

BUG=None
