sunxi: Fix memory 2-rank initialization for a33 cpu
When we initialize the memory we need to autodetect rank and size
but this can happen only if we send the proper reset to both
memory module including cke signal.
For this reason we need initialize the physical on both channel because
we need to presume that both are connected. This way let the CLKE to be
activated at the right time with the memory reset coming from the cpu
