[PowerPC] comment for different input register classes; nfc
Add comments to explain why XXPERMDIs and XXPERMDI have different input register
classes, vsfrc for XXPERMDIs and vsrc for XXPERMDI.
This addresses the comments in abandoned patch D113178, we keep using `f0` instead
of using `vs0` for XXPERMDIs on purpose.
