it85spi: EOL support

This code was originally introduced by ITE for now exceedingly old
Chromebooks. The code has had very little attention to maintain it,
unlikely tested for a long time and now seems to be just a technical
burden to the flashrom project.

If someone is later interested it could be resurrected for reference
from git history. However, it needs quite a bit of work to bring it back
into maintainable order.

Tested: tree builds under meson+make and unit tests pass.
