ARM: 6447/3: sa1100: Put nanoEngine support back in the kernel
Adds Bright Star Engineering's nanoEngine board support to the kernel.
Also:
- Adds the nanoEngine memory chip to arch/arm/mach-sa1100/cpu-sa1110.c
(Micron MT48LC8M16A2TG-75).
- Increase in the sdram_params->name[] field length to accomodate the
name of the memory chip.
- Clean up of header content and order of
arch/arm/mach-sa1100/cpu-sa1110.c
