Added in 2008, but has never had any in-tree users, and no other
architectures provide it. Also remove the header includes that
the commit b41e5fff added to asm/io.h, and add an include of mutex.h
for asm/eeh.h, which relied on io.h including device.h to provide
it.
Tested ppc64_defconfig in an xcompiler, and it passed... no promises
I didn't introduce a header mess on some random variant though.
