Various coldfire fixes: (1) iAudio Bootloader: Check the status of main & remote power button vs. the respective hold switch, and shut down when on hold. On X5/M5 this check is not strictly necessary for the main unit, but left there to keep things uniform. (2) M3: Stop reading the ADC properly before leaving the bootloader, on RoLo, and on reboot, to make it work reliably after those transitions. (3) Disable all interrupt sources on system init to avoid premature ISR calls after enabling interrupts in general. (4) iAudios: Proper implementation of ide_powered(), avoiding nasty HDD clicks in the bootloader when powering down, e.g. because of Hold. (5) Slight optimisations.
