Documentation updates were needed to account for changes caused by the
recent merging of the three acrn-hypervisor, acrn-devicemodel, and
acrn-documentation repos.

Some assumptioins about the doc build process were removed to make it
easier for contributors to build local version of the docs. Assumption
now is that acrn-hypervisor and acrn-devicemodel content is up to date
rather than pulling from upstream on every build.
make pullsource will do an upstream pull manually
make html generates local docs
Also fixed broken link in the README.md file (moved the tech doc root)
