This patch removes a module_exit function that it sgiioc4 should not have had.

Why?  We'd prefer that the module be unloadable, wouldn't we?

It seems that the IDE layer doesn't support that.  sgiioc4 was the only
driver in drivers/ide/pci that had an exit function.  After an unload,
the devices would stay around and the next attempt to reference would
crash...

Thanks,

not supported in the current IDE layer model
(lack of dynamic allocation for ide_hwifs[] and some needed locking)
