Michael Ellerman 51c21e72eb selftests/powerpc: Make context_switch touch FP/altivec/vector by default 
Simply because it touches more code paths that way, and therefore tests
more things.

Michael Ellerman ea0c321784 selftests/powerpc: Make context_switch do something with no args 
For ease of use make the context_switch test do something useful when
called with no arguments.

Default to a 30 second run, using threads, doing yield, and use any
online cpu. Make it print out what it's doing to avoid confusion.
