ARM: i.MX28: Add memory size detection

We can detect the SDRAM automatically, no need to let the boards
do it manually.
This also fixes device tree based i.MX28 boards like the duckbill.
These boards once had a /memory node in the device tree, but now
that this was changed to /memory@40000000 barebox didn't find it
anymore.
