x86: add barrier to read{b,w,l} and write{b,w,l} functions
Use barrier() for memory mapped IO functions.
This fixes pvscsi driver to boot on QEMU's pvscsi controller.
Test command:
qemu -m 512 --enable-kvm -device pvscsi,id=pvscsi0
-device scsi-disk,bus=pvscsi0.0,drive=drive0
-drive id=drive0,if=none,file=ubuntu1410.img,if=none
-bios seabios/out/bios.bin
