Updated the bootloader to use the flash card divider. This will allow wally to run at a faster speed than flash.

Converted over to the blockram/sram memories. Now I just need to cleanup. But before the cleanup I wan to make sure the FPGA synthesizes with these changes and actually keeps the preload.

Partial fix to allow byte write enables with fpga and still get a preload to work.

1. Modified the cache so it can handle the reset delay internally. This removes the mux from the IFU.
...
2. Removed the write address delay from simpleram.sv
3. Fixed rv32tim and rv32ic mode to handle missalignment correctly.
4. Added imperas32i and imperas32c to rv32tim mode.

Added support for logic memory in the IFU and LSU. This disables the bus interface. Peripherals do not work. Also requires using testbench-harvard.sv. I hope to merge this testbench with the main testbench.sv soon.
