flashrom: board_enables: reconstruct table.

This patch restores the pciid based board matching table. It makes this
table readable and hackable again, and the only disadvantage is that the
right margin is way beyond the rather dogmatic 80. All 0x0000 pci ids have
been string replaced by 0 to more easily spot missing ids, and extra
comments have been added to explain how the various entries are used.
