[PATCH] platform/x86: thinkpad_acpi: Fix a max_brightness of thinklight

[Michał Szczepaniak <m.szczepaniak.000@xxxxxxxxx>]

    Thinklight has only two values, on/off so it's reasonable for
    max_brightness to be 0 and 1 as if you write anything between 0 and
    255 it will be 255 anyway so there's no point for it to be 255.

Sending again as I noticed some issues with patch.
