[U-Boot] [PATCH v2 7/8] rockchip: correct the bank0 ram size

[Kever Yang]

The bank0 ram size should be the DRAM size minus reserved size,
the DRAM size may be 1GB, 2GB, 4GB, we can not hard code it.

Changes in v2:
- move the dram_init_banksize() from board file into soc file for we
  have the same setting for different board in one SoC now.
