At least some Sony sensors use "INT" PnP vendor prefix and so telling them
apart from the rest doesn't work at least this way. There could also be
other prefixes as well, they're not all "SONY". Right now there is one with
INT prefix and three with SONY prefix.

If we start having lots of devices with the same quirk, we could also
introduce a pointer to an array of IDs to avoid repeating the same quirk
over and over.

Kate's patch adds two quirks so this could be already considered (and only
one of these IDs is using SONY prefix).
