Commit FS#8379 by Andree Buschmann. Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices. For now, leave base CPU clock at 30MHz, although further savings is possible with some codecs if clock is reduced. Additionally, fix battery capacity on c200 and use my measurements to improve runtime estimation for Sandisk targets.
