Revert "Implemented fix from early issue #16 . Finally decided to pull the"
...
This reverts commit 577cc12fe0#16 . After some discussion, it has
been decided that it is up to the user to implement the pull-up and
pull-down modes correctly by setting the output enable and driving
the output to the appropriate value. Note that this should be well
documented, if by nothing else than a validation testbench that
excercises a user pull-up and pull-down input mode.

Modified the mgmt_protect module to change the tristate outputs to
...
zero level outputs when the user project area is powered down.
That allows the synthesis tools to buffer these outputs. The
protection from floating inputs is left as-is, but all logic that
was unnecessary to be specified by gate instances has been changed
to RTL. This leaves only a handful of signals (logic analyzer input,
user IRQ, and wishbone data out and acknowledge out) to be handled
by explicit logic gate instances.
