DEVELOPERS: drop my packages

I still follow Buildroot development and use it for some personal
projects, but no longer have the time to be an active contributor.
Some of these are important defconfigs and packages to have up-to-date
in Buildroot, and mostly other developers have been doing that work, so
I am dropping them so that someone from the active contributors can be
the maintainer contact for them.
