sunxi: h6/h616: Reuse common DRAM infrastructure
H616 rank and size detection code is superior to the H6. Nevertheless,
they are structurally the same. Split functions from H616 into new file
and reuse them in H6 DRAM driver too. This should also fix some bugs for
H6 too, like incorrect DRAM size detection.
