Add CAN, PWM, ADC and UART1/2/3 support to the LPC176x BSP.

This patch adds support for the following devices to the LPC176x BSP:

  • CAN
  • PWM
  • ADC

It also adds the probe routines for UART1/2/3 to the console_device_table in console-config.c, and enables UART1 in configure.ac.
  • Property mode set to 100755
