got removed from its net by a chang in the LEF view of an I/O pad, and
a lack of declaration of an array to attach to pwr_ctrl_out in the
verilog, which is valid verilog but netgen can't know the bus size
without the no-connect net being declared. The remaining issue has to
do with separation of ground domains in the mgmt_protect block.

verilog RTL files to replace the user area power supply clamp cells with
the new clamped3 cell from open_pdks.
layouts. Because the 1.8V domains are no longer within the pad
ring buses, they need to be connected together in the cell. These
internal lines were previously in the power routing cells.

vccd1/vssd1 and vccd2/vssd2 pads still need to be done, although
the pads themselves have been changed to the base cell, matching
the new verilog RTL.
