ARM: vf610: ddrmc: program Dummy DDRBYTE1/2
The Vybrid reference manual VFXXXRM Rev. 0 10/2016 states in chapter 5.2.6.1 DUMMY PADS (DDR/QuadSPI) that those pads need to be programed for correct operation of DDR. Assume the default DDR pin configuration which seems to work well on a Colibri VF50. Signed-off-by: Stefan Agner <stefan.agner@toradex.com>
