i.MX31/Gigabeat S: The nested IRQ code was just totally wrong and not actually working anyway (which is why it wasn't crashing). AVIC doesn't seem truthful about priority of current ISR either :\. Sometimes there were channel swaps during really active DVFS due to FIFO underflow from a needed long delay in the ISR (100us, and IIS TX only has 45us reserve) and DMARQ *must* be serviced low-latency. Get it doing as was intended.

i.MX31/Gigabeat S: Implement frequency and voltage scaling-- 1.6V for 528MHz, and 1.35V for 264MHz and 132MHz. Keep DPTC overdrive ( > 400MHz) voltage scaling off for now because of uncertainties. Simplify the (working) mess later.

Gigabeat S/i.MX31: Sort files in the /target tree into things that are SoC-generic (into /imx31) and player-specific (into /gigabeat-s, based upon current appearances). Move i2s clock init into the appropriate file. Housekeeping only-- no functional changes.
