[PATCH 2/6] thinkpad-acpi: R52 brightness_mode has been confirmed

[Henrique de Moraes Holschuh <hmh-N3TV7GIv+o9fyO9Q7EP/yw@public.gmane.org>]

We can stop pestering users for confirmation of the brightness_mode
default for firmware TP-76.

While at it, add a few missing comments in that quirk table.
