Add description for missign extensions

This follows the same approach of gpufetch (in
6589de971750b7f4e52c0c35c031fe6204cefdba) where, instead of having a
separate struct for long and short names, both gets merged in a single
struct (ATTRIBUTE_INFO)

This indirectly fixes a bug in RISC-V printer where, if the output
was too large and the short name was selected, it could try to print
an out-of-bound value when accessing the ATTRIBUTE_PEAK. The reason is
that the long and short structures didnt have the same length (because
one attribute name was missing in the short struct). This is now fixed
since we have combined both long and short attribute names.
