Modify initialization to remove ownership step

Modify initialization to remove ownership step

TPM ownership and primary key creation is assumed to be a step that is
executed by the system administrator who will provide the credentials
to pods during startup [Srini]. Now, init only reads the public portion of the
primary key and puts it the host folder.
P9: Remove init.sh. Not needed as initialize will directly talk to device now.
Initialize is called during Step 1 and run_abrmd is called during Step 2
