Fixes the FPGA linux boot after parameterization. Note commit 4d1ddd0c breaks the FPGA again

Created by: rosethompson

• FPGA synthesis is broken. This commit moves closer to fixing the issues causes by parameterization.
• Vivado requires an intermediate wrapper file for parameterization.
• I think the fpga is building again, but the debugger script needs to be updated. For some reason the nets are not present despite being marked debug.
• Updated fpga wally wrapper to work with the ILA.
• Updated fpga wave config.
• FPGA updates.
• Fpga does not correctly boot linux. I think the solution here is to revert out all substantive changes except for parameterization and then add them back in one at a time. This is necessary because the parameterization is not completed in one contiguous group of commits.
• Partially solved fpga boot.
• closer, but the wally32/64priv tests are failing.
• This is at least functionally correct, but has verilator lint issues.
• It's a bit hacky, but the plic now passes the regression test and should be compatible with the fpga.
• Removed unused parameter.
• Updated comments.
