Subject: [PATCH 1/2] resolve issue #862 add description to soc.svd

The issue is that with no description provided it simply would
not put out a description tag, which breaks compatibility with
other programs.

Insert a somewhat useful default description including a timestamp
and the words "LiteX SoC".
