mb/google/brya: Update generic device number for mipi_camera device

If two generic devices use the same number, device coming later
overrides the earlier device, as a result of this the static.c has
only one device.

In the case where we have UFC set to UFC_USB, this will result in
no IPU device scope in SSDT, since its entry will be set to disbled
after UFC probe.

TEST=Build, Boot and Check UFC camera preview with UFC=UFC_USB
