Hi there

The following patch implements idling support for the 8xx.

The patch works on the DUET family and the Normal Low mode
but could also work on other 8xxs easily; I just don't have
access to any other boards.

It's 2.4 for now since most people with 8xx's are on 2.4 still.

By using it on a 870 I see a power savings of ~400mW on a



P.S. Many thanks to Mr. Conn Clark a.k.a. Obscene_CNN,
for it's only patch on an attempt.

P.S #2. There are alot of errata regarding PLPRCR for 8xx,
on older revisions of 8xx. Make sure you read them...
