Tim Edwards 6eb8bb54de Several more LVS corrections, including fixing a label in chip_io that
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.

Tim Edwards a7148378a0 Added as many of the magic database layout files as are expected to remain
unchanged between the caravel and caravel_openframe repositories.
