sh: remove ioport cruft and smc91x from se7343
Remove out-of-date se7343 ioport code including some old support for unknown-ne2000-pcmcia-card, cf-over-pcmcia and a mysterical smc91x that once must have been on a special daughterboard. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
