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.
