[PATCH] 2.6.14 include/asm-arm/arch-ixp4xx/io.h: eliminate warning for pointer passed to integral function argument

[John Bowler]

Fix for a compiler warning, this wasn't apparent in 2.6.12, I
believe the compiler options have been changed (somewhere) so
that passing a (void*) to a (u32) argument is now warned.

This accounts for the majority of the warnings in my builds of
the 2.6.14 kernel for NSLU2.

This is the trivial fix, but may be controversial in that it
simply casts away the warning - the alternative is to change
all the static inlines and potentially some of the callers
thereof.
