- Subject: [m68k] Remove comments copied over from tm.texi
- Organization: Develer S.r.l.
This cleanup would qualify as pre-approved and obvious, but it's best
if other people who worked on m68k have a quick look at it just in
case.

* config/m68k/m68k.h: Remove comments copied over from tm.texi.
Rename 68000 and 68k to m68k for consistency in comments. Remove
trailing whitespace before EOLs and before TABs.
(MAX_CODE_ALIGN): Remove unused macro.
(CALL_USED_REGISTERS): Reformat and add comments.
