fdc: remove sparc sun4m mutations
They were introduced in 6f7e9aec5eb5bdfa57a9e458e391b785c283a007 and
82407d1a4035e5bfefb53ffdcb270872f813b34c and lots of bug fixes were done after that.
This fixes (at least) the detection of the floppy controller on Debian 4.0r9/SPARC,
and SS-5's OBP initialization routine still works.
