qcom: scm: Support register r6 to pass the session id
Non-atomic scm call which could be interrupted, trustzone will store
the session id in a register(r6) which will be used when trustzone resumes
the call.
To avoid r6 being used by compiler, HLOS now uses it to send a zero before
making scm call.
