rk3288: detect sdram size at runtime
we use Kconfig define sdram size before, but there may use
different sdram size in the same overlay, so we must detect
sdram size at runtime now. If we use 4G byte sdram, we can
use[0x00000000:0xff000000], since the [0xff000000:0xffffffff]
is the register space.
