au1000-eth: fix checkpatch errors.

This patch fixes multiple errors reported by checkpatch:
- else not on the ending brace of an if { }
- multiple occurences of for( instead of for (
- c99 comments
- assignment and tests on the same line
- test and statements on the same line
- macro with complex value not between parenthesis
- static variable with initialization value

No functionnal change.
