  Add configuration for the Freescale i.MX53 Quick Start Board.

  Add the Raspberry Pi BSC (I2C compliant) controller driver.

  Add Radxa Rock board (by radxa.com) support.

  Digi-CCWMX53: enable ffec and uart, USB.

  Add support for Freescale Vybrid Family VF600

  Move and rename dwc otg driver to more generic one as it appears to work
  for rk3188 SoC based board too.
