media: qcom: camss: Fix RDI streaming for CSID GEN2

Browse source

Fix streaming from CSIDn RDI1 and RDI2 to VFEn RDI1 and RDI2. A pattern we
have replicated throughout CAMSS where we use the VC number to populate
both the VC fields and port fields of the CSID means that in practice only
VC = 0 on CSIDn:RDI0 to VFEn:RDI0 works.

Fix that for CSID gen2 by separating VC and port. Fix to VC zero as a
bugfix we will look to properly populate the VC field with follow on
patches later.
