Commit 6a0b7505f1fd6769c which added documentation of the virt board
crossed in the post with commit 6f4e1405b91da0d0 which added a new
'mte' machine option. Update the docs to include the new option.

* [PATCH 00/10] target/arm: Various v8.1M minor features

This patchseries implements various minor v8.1M new features,
notably the branch-future and low-overhead-loop extensions.

(None of this will get enabled until we have enough to implement
a CPU model which has v8.1M, which will be the Cortex-M55, but
as usual we can get stuff into the tree gradually.)

Patch 1 is a decodetree fix suggested by Richard that is
necessary to avoid wrong-decode of the changes to t32.decode
by later patches.

thanks
