board: add configuration for freescale twr-vf65gs10 system module

This patch contains configuration for the twr-vf65gs10 system module
of the Freescale (NXP) tower system. It provides support for both the
CMSIS-DAP available via USB and the Cortex+ETM connector
on J5. The configuration also contains DDR and clock init code
hooked into the reset-init event handler.
