gpu: nova-core: set MCTP transport header version to 1
FSP, the GPU's Foundation Security Processor, receives the driver's
messages as packets of MCTP, the Management Component Transport
Protocol. It requires header version 1 in bits 3:0 of the MCTP transport
header.
Nova-core left those bits at zero, so every Chain of Trust request and
every Product Reconfiguration Control request that it sent carried an
invalid transport header.
Declare the version field and set it. Declare the destination endpoint
ID field as well. The driver leaves that field at zero.
