ENGR00216078-2: switch: add L2 switch driver for Vybrid3.0-mvf-201210121659
Port the L2 switch driver from CF platform for Vybridi plaform. This driver usually should work together with the RSTP demo applications provided by fsl. Signed-off-by: Alison Wang <b18965@freescale.com> Signed-off-by: Jason Jin <Jason.jin@freescale.com>
