I'm ok with this as long as there aren't going to be future rockchip
tweaks to the driver that will need to be separate from those already
there (ie: versioned). In the tegra driver, the product numbers serve
to represent the first product with said feature or quirk, the same
could have been done here.

However, if we know that all rockchip devices in the future will not
need to differentiate from each other, this seems fine.
