Remove warnings from compilation of the s2892 with and without CBFS.

I didn't try to remove "defined but not used" warnings because there are too
many ifdefs to be sure I wouldn't break something.

For shadowed variable declarations I renamed the inner-most variable.  

The one in src/pc80/keyboard.c might need help.  I didn't change the
functionality but it looks like a bug.

I boot tested it on s2892 and abuild tested it.
