all pin names should be wrapped into a function/property. This ensures

before the names of bl/br from the bitcell were assumed. If we want to
allow renaming of bl/br from bitcells, we have to seperate the other
modules from that. Note, that we don't touch every occurence of bl/br,
but only the once necessary that pin renaming of the bitcell works.
