[flashrom] dell s1850

[Carl-Daniel Hailfinger]

Hi Ron,

here's an incomplete patch. Is is missing the exact GPIO number, but the
datasheet is clear that the GPIO must be between 16 and 31 (inclusive).
GPIOs below 16 are input only and thus unusable for flash write enables.

Please send complete output of "lspci -nnvvxxx" so I can find a suitable
set of PCI devices to match on for the board_enable array.

As stated above, the patch is missing PCI IDs for the board enable array
and the exact GPIO number (XX). That's it.
