Location constraints in pin.cfg cause OpenLane flow to fail

[abdullahyildiz]

Some pin location constraints in pin.cfg files seems to have wrong syntax.

make cbx_1__0_ command fails with the following error:

Top-level design name: cbx_1__0_                                                                                                                                                                            
Error: Multiple regexes matched top_width_0_height_0__pin_11_lower . Those are top_width_0_height_0__pin_[1][0-9]_lower.*$ and top_width_0_height_0__pin_11_lower.*$ 

The error message points to pin.cfg file:

Flow completes for cbx_1__0_ with the following changes in the respective pin.cfg:
