d2: Raise ION_MM_SIZE

From 96MB to 108MB

This was previously tried in CM10.1 but the size increase was to aggressive.
Still might not be the perfect size but does allow the ability to use
Instagram Video and not cause Youtube HD video playback issues.  I believe
something else needs to be tweaked for a complete fix, but this helps.
