From: Paul Elder <paul.elder@xxxxxxxxxxxxxxxx>
The ISP supports both CSI and parallel interfaces, where port 0
corresponds to the former and port 1 corresponds to the latter. Since
the i.MX8MP's ISPs are connected by the parallel interface to the CSI
receiver, set them both to port 1.

Changes since v3:
- Add comment regarding the IMX8MP_CLK_MEDIA_ISP clock rate
- Fix assigned-clock-rates
- Dropping Tested-by as the clock configuration has changed
Changes since v2:
- Assign clock parent and frequency in blk-ctrl
Changes since v1:
- Fix clock ordering
- Add #address-cells and #size-cells to ports nodes
