CONFIG symbols that are hardware parameters rather than user-tweakable
config go in the CONFIG_SYS namespace (see "Software Configuration" in
README).
I think it should also be an FSMC-specific parameter, not something that
looks universal.

The struct name takes that role here; hardware documentation doesn't
have the benefit of that.
