Kernel: Don't compile ISA IDE controller code in non-x86 builds

The ISA IDE controller code makes sense to be compiled in a x86 build as
it relies on access to the x86 IO space. For other architectures, we can
just omit the code as there's no way we can use that code again.
To ensure we can omit the code easily, we move it to the Arch/x86
directory.
