[ARM] 3589/1: AT91RM9200 DK/EK board update

Patch from Andrew Victor

This patch updates the support for the Atmel DK and EK boards.

The changes include:
1. Use the new at91_uart_config structure and device registration
functions for the UARTs.
2. Registration of I2C and SPI platform devices.
3. The USB Device pullup line is connected to reset, so multidrive needs
to be enabled on the line.  [Patch from David Brownell].
