[PATCH RFC 07/11] media: rockchip: rkisp1: carry ip version information

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner at theobroma-systems.com>

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.
