platform: dce: Add bootsrap2 command

Browse Source 
Add support to the bootstrap command over the admin channel,
which will be called when a client registers. This command will
perform steps that must be performed only after the client is ready.

TODO: This bootstrap-2 command will be replaced by the existing
bootstrap command which we call during DCE-FW bootstrapping once
we split admin bootstrapping and RM bootstrapping in the DCE-KMD.
