Kernel panic - not syncing: Fatal exception in interrupt

This is because the macro operations in smc91x.h defined
for Versatile are missing SMC_outsw() as used in this
commit.

The Versatile needs and uses the same accessors as the other
platforms in the first if(...) clause, just switch it to using
that and we have one problem less to worry about.

This includes a hunk of a patch from Will Deacon fixin
the other 32bit platforms as well: Innokom, Ramses, PXA,
PCM027.

Checkpatch complains about spacing, but I have opted to
follow the style of this .h-file.
