The GIGABYTE GA-7ZM has a maximum decode size (parallel chips) of 512 KB
Add this information to the new field in the board-enable table. We match the board via two sets of PCI IDs. However, as we don't need a board-enable function for this board (it works out of the box; well, at least if you remove the JP9 jumper on the board), change the code to allow NULL as value for the board-enable function. There will likely be more boards in the future where we want to record a maximum decode size but which don't need a board-enable. This is hardware-tested on the GIGABYTE GA-7ZM by successfully writing a 512KB image of random bytes to a chip in this board. Corresponding to flashrom svn r885.
