[U-Boot] [PATCH 05/11] arm: cm4008, cm41xx: set gd->ram_size in dram_init

Leave dram_init_banksize to set up the bank info data.
ram_size was previously uninitialized.
Also put data on SDRAM configuration in header file.

Changes for v2:
- Update to use CONFIG_SYS_SDRAM_ constants
- Update cm41xx also
- Map SDRAM to match configuration
Changes for v3:
- Moved SDRAM configuration to header file, in
preparation for lowlevel constant cleanup.
