powerpc: Drop include of linux/io.h from asm/io.h
Currently powerpc's asm/io.h includes linux/io.h, and linux/io.h
includes asm/io.h.
This can cause problems because depending on which is included first the
order of definitions between the two files will change.
The include of linux/io.h was added back in 2008 in commit b41e5fffe8b8
("[POWERPC] devres: Add devm_ioremap_prot()"). It's not entirely clear
it was needed then, but devm_ioremap_prot() has since been removed
entirely as unused, in dedd24a12fe6 ("powerpc: Remove unused
devm_ioremap_prot()").
So it seems to be unnecessary and can potentially cause problems, so
remove the include of linux/io.h from asm/io.h
