driver: vi: tegra_camera: correct pdev->id for DT

DT will initialize the pdev->id as -1 for both vi.0 and vi.1. This
will cause several subtle issues since checking pdev->id is used a
in VI and Tegra V4L2 camera drivers.

Set the pdev->id as the right value during probing for DT case. Then
no change is need for others
