media: qcom: camss: csid-340: Fix unused variables

The CSID driver has some unused variables and function parameters
that are no longer needed (due to refactoring). Clean up those
unused elements:

- Remove the `vc` parameter from `__csid_configure_rx()`.
- Drop the unused `lane_cnt` variable.
- Adjust call to `__csid_configure_rx()` accordingly.
