[PATCH v2 6/6] soc: qcom: rpmpd/rpmhpd: Add a max vote on all corners at init

[Rajendra Nayak]

As we move from no clients/consumers in kernel voting on corners,
to *some* voting and some not voting, we might end up in a situation
where the clients which remove votes can adversly impact others
who still don't have a way to vote.

To avoid this situation, have a max vote on all corners at init.
This should/can be removed once we have all clients moved to
be able to vote/unvote for themselves.
