KVM: PPC: Add helper functions to call real mode loaders
Linux contains quite some bits of code to load FPU, Altivec and VSX lazily for a task. It calls those bits in real mode, coming from an interrupt handler. For KVM we better reuse those, so let's wrap a bit of trampoline magic around them and then we can call them from normal module code.
