Couple of spelling mistakes here, they got copied into the zc706 patch too.

Setting QB_MACHINE is not needed as qemuboot-xilinx.bbclass sets this
via a "_arm" override.

Also so users can observe the support easily could you update the
README for these machines, but use "(with QEMU support)" wording
instead of just "(QEMU support)" (the previous wording is a bit
ambiguous).
