[ Upstream commit c46f16f156ac58afcf4addc850bb5dfbca77b9fc ]
This makes the driver work with the new check in v4l2_async_register_subdev() that was introduced recently in 6.6-rc1. Without this change, probe fails with:
ov8858 1-0036: Detected OV8858 sensor, revision 0xb2 ov8858 1-0036: sub-device fwnode is an endpoint! ov8858 1-0036: v4l2 async register subdev failed ov8858: probe of 1-0036 failed with error -22
This also simplifies the driver a bit.
