Add support for MtFuji elba dpu

This patchset adds sonic buildimage support for AMD-Pensando DPU on MtFuji DSS.
MtFuji is a DSS being developed in collaboration with AMD-Pensando and
Cisco for data center applications.
MtFuji mounts elba based nic which is an AMD-Pensando PCI Distributed
Services Card (DSC) whose support has been added in SONiC.

The changes are verified on Pensando DSS-MTFUJI card.
There is one 200G uplink port and no management port.
The link and traffic has been tested on the port.
