media: rockchip: rkisp1: carry ip version information
From: Heiko Stuebner <heiko.stuebner@...> Date: Wed, 6 Jan 2021 23:00:53 +0100
Commit-Message
The IP block evolved from its rk3288/rk3399 base and the vendor designates them with a numerical version. rk3399 for example is designated V10 probably meaning V1.0. There doesn't seem to be an actual version register we could read that information from, so allow the match_data to carry that information for future differentiation.
