  1. More developments with BOOT 

    The CPU is reading things from somewhere (I didn't get to check where
from, but instruction data is arriving) - but something's not right
because it doesn't try to write anything (wdata always xxxx) and preboot
tells the CPU to write the bootloader to memory.

List of changes:
- There are 2 SWRegs now, one for the CPU reset pulse and another one to
  store the current boot stage.
- Full ROM removed, and instead there are only the preboot and
  bootloader separate ROMs, and only the bootloader one goes into the
  ROM SWReg.
- Correction in concatenation order in iob_soc.v (was inverted).
- CPU pulse request created and possibly ready inside iob_soc_boot.v.
