Tim Edwards ba932643e6 Changed the chip_io and chip_io_alt layouts to implement the
continuous ring of vccd and vssd.  The clamp connections for the
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.

angles on metal5.

Tim Edwards dd66d1e5ca Renamed the poorly and awkwardly named "sky130_fd_sc_hvl__lsbufhv2lv_1_wrapped"
cell to the simpler (and easier to remember) "xres_buf".

Tim Edwards 3a57940371 Revised the management protect block to include protections against
an unconnected wishbone bus (unconnected inputs).  Added the missing
signals for the user IRQ enables to management protect (which have
to come from the management SoC).

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.
