cpuidle: psci: Extend information in log about OSI/PC mode
[ Upstream commit 668057b07db069daac3ca4e4978f8373db9cb71c ]
It's useful to understand whether we are using OS-initiated (OSI) mode or
Platform Coordinated (PC) mode, when initializing the CPU PM domains.
Therefore, let's extend the print in the log after a successful probe with
this information.
