Configure Gigabeat S with EABI compiler by default. Implement the INIT section that this enables (due to selective need for long calls). Remove pcm_postinit from INIT section since it's asynchronous. Disable strict aliasing on SPC codec for now just to shut it up.

i.MX31/Gigabeat S minor cleaning: Make HW access more obvious in places I forgot to do earlier. Reduce the number of structs that need to be filled-out for some drivers just to simplify a little. Change some types.

i.MX31/Gigabeat S: Actually enable DPTC which can set optimal voltage for 528MHz. Requires an SPI and PMIC interface rework because of the low-latency needs for the DPTC to work best with minimal panicing. SPI can work with multitasking and asynchronously from interrupt handlers or normal code.

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: Continue, and most likely complete, the platform/player-specific code/data shuffling begun in r25547.

Gigabeat S: Slow down the SPI clock to 1/8 current speed. It seems lower voltages can reveal the weakness that forbids maximum-speed clocking per the SPI spec. OF leaves it set much slower. Push it a bit over OF since it's been gotten away with fairly cleanly so far. Settings on pins and interface to be more thoroughly investigated.

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.
