Tim Edwards 7bfab382d8 After updating from the PR that adds the gate level chip_io_openframe.v, 
modified it so that it matches the modified chip_io_openframe layout
in this PR (namely, the GPIO "_wrapped" pads are replaced with the
equivalent non-wrapped base cells).

Tim Edwards 31c8f54f24 Modified the openframe padframe so that the GPIO "wrapped" 
cells are replaced with the base cells.  Routing to pins
is instead done in the "gpio_connects" cells while
improving on the original routing (fewer cross-overs,
multiple vias per contact, wider buses for the analog
signals).  Made small adjustments to many of the openframe
wrapper pins to keep them all on a 10nm grid.  Moved the
connections previously from the "wrapped" GPIO cell back
from the openframe project border, so that the border can
be clear of all blockages.  Added the DEF file of the
wrapper (previously only in the openframe example repo)
to the def/ directory.  Note:  The modified LVS scripts
depend on the gate-level netlists of the frame, which
have been committed in a prior pull request.  This pull
request does not conflict with those files.

Tim Edwards e2cc50bae3 Copied housekeeping.v to housekeeping_alt.v and extended the 
function for clock routing to include GPIO[30] and GPIO[31], for
use with the caravan chip, which does not have GPIO in locations
14 and 15.  This restores the clock monitoring capability for
caravan.  Eventually, the housekeeping_alt module should become
the only housekeeping module, extending the clock monitoring
function for caravel and allowing the same module to be used for
both caravel and caravan.
