The AHCI code doesn't rely on x86 IO at all as it only uses memory mapped IO so we can simply remove the header. We also simply don't use x86 IO in the Intel graphics driver, so we can simply remove the include of the x86 IO header there too. Everything else was a bunch of stale includes to the x86 IO header and are actually not necessary, so let's remove them to make it easier to compile non-x86 Kernel builds.
