We forgot to shift the addresses for continuation bytes in r1840. Also, probe_en29lv640b() can easily be replaced with refined probe_jedec(). Furthermore, add EN29LV640T which is the top boot sector-variant of EN29LV640B.

Rudolf, if you still have access to the bifferboard, I'd very welcome testing this patch on it. This would verify the change we did in r1840 (+ its fix in this patch) + the refactoring as well.
I might look into the write function later too, but currently probing functions are my main focus.
Actually I don't see anything unusual in the datasheet regarding writing either, where does it state that the chip has to be programmed in 16b words even if BYTE# is low?. I am not 100% if jedec_probe needs a refinement for shifted access too, but we should be able to get this to work in any case without an extra function, Carl-Daniel, please advice. :)
PS: I have removed probe_en29lv640b() locally which I forgot on the posted patch.
