staging: pi433: remove TODOs-related item from the TODO file

All occurences of code annotated with TODO in this driver have been
addressed in the last couple of years by the community. The last
occurrence of the word "TODO" was in the form of a multi-line comment in
the header file intended to be exposed to userspace once this driver
moves away from the staging folder.

This patch removes that TODO as well as the TODO-related item from the
driver's TODO file
