media: i2c: imx290: Add configurable link frequency and pixel rate

Commit 98e0500eadb772e1be32d8e369fcc3b7bcac93ed upstream.

IMX290 operates with multiple link frequency and pixel rate combinations.
The initial driver used a single setting for both but since we now have
the lane count support in place, let's add configurable link frequency
and pixel rate.
