i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well.

i.MX31: Busy wait for a couple microseconds at most then sleep until next tick when polling drive status. This prevents pointless jumps to overdrive speed from perceived high load when waiting for lengthy ops to complete such as spinup and sleep.

Some static data is only used by .init functions. Add .initdata to declare such data (otherwise section conflicts arise). For i.MX31, use INITDATA_ATTR in the appropriate places.

Introduce NORETURN_ATTR wrapper for __attribute__((noreturn)), using this and a bit further cleanup in main gets rid of a warning when compiling for android.

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: 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.
