sunxi: add R528/T113-s3/D1(s) DRAM initialisation code
The Allwinner R528/T113-s/D1/D1s SoCs all share the same die, so use the
same DRAM initialisation code.
Make use of prior art here and lift some code from awboot[1], which
carried init code based on earlier decompilation efforts, but with a
GPL2 license tag.
This code has been heavily reworked and cleaned up, to match previous
DRAM routines for other SoCs, and also to be closer to U-Boot's coding
style and support routines.
The actual DRAM chip timing parameters are included in the main file,
since they cover all DRAM types, and are protected by a new Kconfig
CONFIG_SUNXI_DRAM_TYPE symbol, which allows the compiler to pick only
the relevant settings, at build time.
The relevant DRAM chips/board specific configuration parameters are
delivered via Kconfig, so this code here should work for all supported
SoCs and DRAM chips combinations.
