docs: add inital lts doc

Ref: https://linaro.atlassian.net/browse/TFC-669

The initial LTS document was created as pdf and was maintained in a
shared folder location, to avoid pdf getting lost and trying to find
where it is we decided to have LTS details part of docs in TF-A.

This patch directly reflects the data from pdf attached to TFC-669.
Any improvements or amends to this will be done at later phases based
on LTS maintainers comments and agreements.
