microblaze: drop unneeded semicolon

microblaze: drop unneeded semicolon

When a function-like macro expands to an expression, that expression
doesn't need a semicolon after it.  All uses have been verified to
have their own semicolons.

This was found using the following Coccinelle semantic patch:

@r@
identifier i : script:ocaml() { String.lowercase_ascii i = i };
expression e;
@@

*#define i(...) e;
