FPGA: Add CPU instruction address SPI access control
Add logic that checks if the CPU is reading an instruction
      to execute from ROM or not. If instructions are read
      from ROM, access to the SPI from the API is granted, and
      signals between the SPI master and a slave are allowed.

      If instructions are not read from ROM, any API access
      is blocked. and between the SPI master and a
      slave are disabled.
