sunxi: H616: DRAM: Adjust size scan procedure

It's safer to start scanning for columns first and then rows. Columns
reside on LSB address pins, which means that second configuration will
already have all needed row pins active.

This is also preparation for introducing DDR4 support, which need scan
for banks and bank groups too.
