Subject: [PATCH RESEND] leds-ot200: Fix error caused by shifted mask

During the development of this driver an in-house register
documentation was used. The last weeks some integration tests
were done and this problem was found. It turned out that
the released register documentation is wrong.

The fix is very simple: shift all mask by one.
