This patchseries adds SME2 support to the gdbstub. This is
fairly straightforward as the only thing we need to do is
expose the new ZT0 register in the XML in the way that gdb
documents that we should.

Patch 2 adds the TLS section that we should in theory have
been exposing already; this mostly will become relevant when
gdb implements the SME lazy-state-handling that uses TPIDR2.

Patch 3 is a simple "check reads and writes" test case along
the lines of our existing SME tests.

Changes v1->v2:
 * use static XML for the sme2 section, not dynamic
 * add patch 2 for the tls section
 * tidy up some excessively cut-n-pasted stuff in the
   testcase script

thanks
