    Add a bs_barrier to make ThunderX xhci work.  Not sure why this is
    needed, but I'll work it out later.

Turns out bus_dma.c needed fixing which I did with

    revision 1.115
    date: 2019-06-14 10:09:12 +0100;  author: skrll;  state: Exp;  lines: +39 -34;  commitid: GKW2p7ijoslyu8rB;
    Simplify the _ARM32_NEED_BUS_DMA_BOUNCE #ifdefs and rely on compiler
    optimisation of the bouncing = false case.

    Drain the write buf (aka DSB) in more cases

    Catch all CPUs that support speculation. (thunderx isn't CPU_CORTEX)
