Adds the ability to force dual panel at any dpi (2/3)

This allows tablet mode with single panel and also
allows regular phoneUI with dual panel .
This will only affect apps with dependencies to
framework-res.apk , in other words gapps email.apk etc are not affected.
**Im curious to see how it behaves in tablet device the default
shoudl stick.
