Create disk encryption key before framework start

HW based disk encryption creates key in secure side. Key creation
can take sometime to create the key securely. If framework is
started before creating the key, it is possible that framework
requests service from secure side. Secure side can serve mostly one
request at a time. Secure side may reject framework request if key
creation request is still going on. This may cause problem in the
system
