viafb: merge the remaining output path with enable functions
This patch merges the remaining functionality of the output path function in the associated enabling functions. This is very natural as most of the remaining code does actually enable the device. Just some more or less intelligent code merge. If no stupid mistakes occured there should be no regressions.
