serprog: Fix FWH/LPC by implementing serprog_map
The serprog protocol does only transmit 24 bit-wide address and ignores the top 8 bit. This is fine as long as the underlying hardware ignores the latter anyway (which is the case for parallel chips that even lack the respective pins). FWH/LPC chips, however, operate on a full 32-bit (LPC) or 28-bit (FWH) address space and would fail with the fallback mapping to NULL. Corresponding to flashrom svn r1895.
