IMX290_REG_SIZE_SHIFT instead of 16 here? Not exactly necessary, but use
1U, 2U and 3U instead.

While I agree with the intention, it fails for some devices, e.g. Vision 
Components MIPI IMX327 C does not support auto-increment and most probably 
also valid for the IMX290 model.
This is similar to the OV9281 variant, see [1].

Reading ID using 16bit register (using later patch) returns:
> imx290 2-001a: chip ID 0xffd0
Using 2 8bit reads:
imx290 2-001a: chip ID 0x07d0

Best regards,
Alexander
