fix(plat/marvell/a8k): Add missing build dependency for BLE target

BLE source files depend on external Marvell mv-ddr-marvell tree
(specified in $(MV_DDR_PATH) variable) and its header files. Add
dependency on $(MV_DDR_LIB) target which checks that variable
$(MV_DDR_PATH) is correctly set and ensures that make completes
compilation of mv-ddr-marvell tree.
