serprog: Fix FWH/LPC by implementing serprog_map

Browse Source 
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.
