New Revision: 885

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.
