This cleans up the SDRAM initialization and related code a bit, and
allows faster booting.
* Add definitions for EBI and internal SRAM to asm/arch/memory-map.h
* Remove memory test from sdram_init() and make caller responsible
for verifying the SDRAM and determining its size.
* Remove base_address member from struct sdram_config (was sdram_info)
* Add data_bits member to struct sdram_config and kill CFG_SDRAM_16BIT
* Add support for a common STK1000 hack: 16MB SDRAM instead of 8.

Make STK1002 and NGW100 boards act more alike:
- STK boards can use as many arguments as NGW
- STK boards don't need to manage FPGAs either
- NGW commands should match STK ones
Also spell U-Boot right in prompts for STK1002 and NGW100.

The default load address is SDRAM + 2MB, not SDRAM + 4MB. The latter
wouldn't have worked anyway since the board can only access 4MB of
SDRAM.
