Subject: [RFC v3 7/7] arm64: Juno: declare idle-state cluster-sleep-0 as genpd state

From: Marc Titinger <mtitinger@...libre.com>

Using Juno to exercise the code that prepares for OS-initiated idle-state
handling, using genpd platform callbacks. In opposition to platform-
initiated mode as currently with pcsi/ATF.
