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 Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
