arm-trusted-firmware-mvebu: fix commit ids to for mv-ddr-marvell

without this patch a3700-utils/tim/ddr/ddr_tool.verstr contains the OpenWrt commit ID.
this patch fix the mv_ddr version commit ID by using the global variable MV_DDR_COMMIT_ID.

Upon boot it now prints "mv_ddr-devel-g02e23dbc-d DDR4 16b 1GB 1CS".
