update caravel with tying `porb_h_in` with `por_l_in` (#326)
* update caravel with tying `porb_h_in` with `por_l_in` at the `mgmt_core_wrapper` in the top-level layout:
- `porb_h_in` shouldn't be left floating as it is an input to `clkbuf_16`

* add caravel-eco.gds (same as caravel.gds)

Tim Edwards 69d353f65c Corrected the verilog and the layout for the caravan version of the
signal buffering (verilog was missing one of the buffers, and the
layout had some of the labels at the top accidentally erased).

Tim Edwards f7e2dc80a6 Made a minor correction to the layout to remove an extra unused
buffer.  This does not affect ongoing top-level routing work, but
is needed for LVS.

Tim Edwards 48ae31205c Another change to the pin endpoint positions to make sure that they
have at least 0.28um spacing to the next wire.  Not sure that this
is going to solve the router errors, though.
