sparc: io: remove duplicate relaxed accessors on sparc32

Browse Source 
Commit 1191ccb34c ("sparc: io: implement dummy relaxed accessor
macros for writes") added the relaxed accessors (readl_relaxed etc) in
a file that is shared between sparc32 and sparc64. However, the earlier
e1039fb426 ("sparc32: introduce asm-generic/io.h") had already changed
the sparc32 implementation to use asm-generic/io.h, which provides the
same macros, resulting in lots of build errors.

This moves the definitions from the shared sparc file into the
sparc64-only file to fix the sparc32 build regression.
