[U-Boot] [PATCH v2 1/6] sunxi: makes an invisible option for H3-like DRAM controllers

Allwinner SoCs after H3 (e.g. A64, H5, R40, V3s) uses a H3-like
DesignWare DRAM controller, which do not have official free DRAM
initialization code, but can use modified dram_sun8i_h3.c.
Add a invisible option for easier DRAM initialization code reuse.

Changes since v1:
- rename the option to SUNXI_DW_DRAM.
