> Store first known production revid into the device info.
> 
> This enables us to easily see if we are running on
> a preproduction hardware.
> 
> Uninitialized (zero) product revision id means that
> there are no known preliminary hardware for this platform,
> or that the platform is of gen that we don't care.
> This is all pre gen9 platforms.
> 
> Unknown product revision maps to REVID_FOREVER on a
> gen9+ platforms on default. When the platform
> gets the first production revision and our testing
> infra is cleaned from preproduction hardware, we can
> set a first production revid. At that point we start
> to complain about running driver on preliminary hardware.
> 
> v2: initialize GEN9_FEATURES too (CI)
> v3: comment, eyesore fix (Chris), cfl fix, squash
