ddr: fsl: fix possible use of uninitalized variable
step_assign_addresses_interleaved() contains a loop that either sets
total_mem to a fixed value or keeps incrementing it.
If we exclusively run into the "keep incrementing it"-case, we would
start with an uninitialized total_mem. Fix this by initializing it to 0.
