Tim Edwards 5d3f2a26f4 Corrected the Caravel layout and the Caravel and Caravan GL netlists 
to resolve the problem with the typo that caused the propagated
GPIO serial load, reset, and clock signals to get scrambled on the
user2 side.  Caravel is now LVS clean again (Caravan needs layout
work).

Tim Edwards 08a2c90940 Made updates to correct LVS errors in caravan. Found one major error in the RTL 
verilog for both caravel and caravan.  Hand-edited the RTL and GL netlists to
correct this;  still need to correct the layouts.  The error causes the user1
side clock, load, and reset buffers to drive the user2 side as well as the user1
side, making a huge mess of the routing.  Will route this by hand.

Tim Edwards cd68a2aeff Made several corrections to errors found in the netlists: (1) 
Fixed rstb_h, which was being input to low-voltage blocks.  (2)
Fixed flash_csb_ieb_core and flash_clk_ieb_core, which were not
output from housekeeping as they should be;  the solution was
to tie the INP_DIS lines low at the pad by connecting them to
the TIE_LO_ESD line.  This should probably be addressed in
housekeeping but would change the current pinout.
