[PATCH] ath79: use common device definition for Buffalo devices

[Adrian Schmutzler]

The Buffalo devices in ath79 share their image generation code,
so let's create a shared Device definition for them.

Since most of them use BUFFALO_HWVER := 3, this is moved as
default to the shared definition as well.
