[PATCH] s3c2410: remove __ioaddrc()

From: Cesar Eduardo Barros

While looking at s3c2410's mach/io.h, I noticed the #define for
__ioaddr() looked wrong. While the #defines above it called the "c"
suffixed variant when __builtin_constant_p() was true, the one for
__ioaddr() called the "c" suffixed variant (__ioaddrc()) when
__builtin_constant_p() was *false*.

Looking further, I noticed that __ioaddr() and __ioaddrc() were
identical, the only difference being that __ioaddr() is an inline
function and __ioaddrc() is a macro.

__ioaddrc() is not used anywhere else. There were similar constructs,
also reversed from what I'd expect, in both mach-clps7500 (removed from
the kernel in 2.6.29) and mach-rpc. The copy in mach-rpc was removed in
commit 6de2c31d3dad7384b3efa03674bd6ed479d58cb2 (rpc: remove obsolete IO

Since __ioaddrc() is both redundant and useless, has no other uses, and
has already been removed in mach-rpc, remove it also in mach-s3c2410.
