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 340 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.
