Bastian Koppelmann 76256a2f1b sense_amp: Allow custom pin names 
we don't want to propagate the sense amp's bl/br names out of the
sense_amp_array. Thus the sense_amp_array gets them named as
"bl"/"br" again.

Bastian Koppelmann 680dc6d2c7 sense_amp/array: Remove hardcoded pin names 
all pin names should be wrapped into a function/property. This ensures
that there is exactly one place to change the name.

Bastian Koppelmann f9babcf666 port_data: Each submodule now specifies their bl/br names 
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.
