Remove atomic register bit manipulation functions from i.MX and s3c target code and introduce generic functions for ARM (bitmod32, bitset32, and bitclr32). Multiprocessor support is possible but just not implemented at the moment, only interrupt lockout.

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.
