[src/trunk]: src/sys/dev/rasops Misc style clean up's.



details:   https://anonhg.NetBSD.org/src/rev/a0ee8f0be5ce
branches:  trunk
changeset: 458773:a0ee8f0be5ce
user:      rin <rin%NetBSD.org@localhost>
date:      Sat Aug 10 01:24:17 2019 +0000

description:
Misc style clean up's.
- Introduce and use proper macros.
- Use not ambiguous variable names.
- Unify similar functions as possible as I can.
- G/C unused headers.
- Use #include <dev/rasops/foo.h> instead of "foo.h"
No particular functional changes intended.
