i.MX25 3DS fixes and enhancements

This series of patches includes the following:

1. Fixes and clean-ups for the i.MX25 3DS board code
2. New driver for the i.MX25 3DS on-board PMIC
3. Enable proper FEC initialization including PHY power supply enable
4. Add support for boot from UART on the i.MX25 3DS

Note that currently there is no watchdog service routine. Since the UART boot mode enables the watchdog, this means that you can only have Barebox running for 90 seconds before the watchdog resets the CPU.
