Revert "scripts/gdb: add documentation example for radix tree" 

This reverts commit 9b558035 ("scripts/gdb: add documentation
example for radix tree")

The python implementation of radix tree was merged at the same time as a
refactoring of the radix tree implementation and doesn't work.  The
feature is being reverted, thus we revert the documentation as well.

 o Dig into a radix tree data structure, such as the IRQ descriptors:
