[AArch64/PATCH 1/2 (v2)] Add xgene1, while retaining xgene-1 for compatibility.

[Philipp Tomsich <philipp dot tomsich at theobroma-systems dot com>]

This change has been lingering unmerged for a while and the xgene-1
name has never been widely used in other tools. All other patches
(e.g. gcc) and common usage in the wild has always been through the
'xgene1' identifier.

As per Marcus' comment: we now support both names, as 'xgene-1' has
been in the wild with the binutils-2.25 release.

The deprecated name 'xgene-1' has been removed from the documenetation
to avoid confusion.
