Use \dynamicUp

The dynamicUp macro and many more useful macros are defined
in the file ly/property.ly (called ly/property-init.ly in
version 1.5.x). There you'll also find out what property
you could have used. They should definitely be listed in 
the documentation.

In general, you can find the different properties by browsing
the section "Lilypond Internals" in the on-line manual, but
in this specific case it's not that intuitive that you should
set the direction of DynamicLineSpanner, not on Hairpin.
