Repository for PLDM

[Deepak Kodihalli]

Hi Brad,

Could you help create a repo for PLDM? The design is still under review 
on Gerrit, but there's enough clarity on some aspects to start making 
contributions.

PLDM will be a daemon and libs, but I'm thinking all that can be housed 
in a single repo called pldm.

Thanks,
Deepak
