Removing useful features is deprecated too.

The best reason I can see for removing the __setup parameters is that the 
g_NCR5380 module parameters clash with those of the g_NCR5380_mmio module 
(when both are built-in). But only a custom kernel would configure them as 
built-in drivers, and it probably would not have both drivers enabled. So 
a clash seems unlikely.

Anyway, Christoph seems to be OK with this so I won't object. But if you 
assume that no-one has built-in g_NCR5380{,_mmio} drivers, or you believe 
that the benefit outweighs the inconvenience of the breakage caused, then 
the commit log should explain that.
