Lightbar attributes are hidden if the ID of the device is not 0
(the assumption being that 0 = cros_ec = might have a lightbar,
1 = cros_pd = hide); however, sometimes these devices get IDs 1
and 2 (or something else) instead of IDs 0 and 1. This prevents
the lightbar attributes from appearing when they should.
Proposed change is to instead check whether the name assigned to
the device is CROS_EC_DEV_NAME (true for cros_ec, false for cros_pd).
