testing/linux-tools: package GPIO+IIO tools
depends="cpupower perf" from linux-tools:
- I'm not sure how useful it is (Do you really want all Linux tools at the same time?)
- At the moment the dependency leaks into all subpackages (e.g. linux-tools-iio also has a dependency on cpupower/perf)
Not sure about this, could do
depends="" in all subpackages alternatively.
