Effectively reverted the change to add spare logic blocks near each (#157) 
* Effectively reverted the change to add spare logic blocks near each
of the GPIO control blocks by changing the definition of
NUM_SPARE_BLOCKS to 4 (the original number of spare logic blocks)
for both caravel and caravan top level RTL verilog modules.

* Apply automatic changes to Manifest and README.rst

kareem 6d1d618974 reharden!: gpio_control_block 
- rtl updated
~ add one column to the right to pass placement congestion
~ density adjusted (probably has no effect)
+ manually add isosubstrate layer in mag and gds from older iterations

!important still need to run dynamic simulations
!important depends on some updates to openlane
!important need to be able to recreate using newer openlane versions

Added spare logic blocks for GPIO (#153) 
* Added enough spare logic blocks to have the existing four above
the processor, plus one each per GPIO (38 for caravel, 27 for
caravan).

Tim Edwards 42805f767e Removed some references to mgmt_soc_litex files that had been added 
to caravel_netlists.v when attempting to determine if the
verification testbenches could be run from caravel referencing
caravel_mgmt_soc_litex instead of the other way around.  This file
has been reverted back to its original form.

Tim Edwards e2556cc11b Removed the SPARE_LOGIC_BLOCK ifdef...endif from around the spare 
logic in caravel.v and caravan.v.  These had been added to the
caravel_stanford branch because the spare logic blocks are not
usefully synthesizable.

Tim Edwards 72341326e2 Corrected a typo in the definition of the mgmt_io_oeb vector in 
caravel.v, which should be the same as mgmt_io_in and mgmt_io_out
and should equal the number of user I/O pads (38).

Tim Edwards f5a9d4677e Revert "Implemented fix from early issue #16. Finally decided to pull the" 
This reverts commit 577cc12fe0.

Reverting the change from issue #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.
