[ARM] 3588/1: AT91RM9200 CSB337/637 board update

Patch from Andrew Victor

This patch updates the support for the Cogent CSB337 and CSB637 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 CSB337 board uses PB0 & PB1 (and not PB2) for the LEDs.  [Patch
from David Brownell]
