[PATCH 4/6] include/configs: aspeed: Remove hardcoded variables

[Chia-Wei, Wang]

The hardcoded platform variables such as DRAM base address are not
common to Aspeed SoCs AST24xx/AST25xx/AST26xx. This patch replaces
those hardcoded with macros defined in a newly added header, where
the basic SoC HW information are assigned accordingly.
