[PATCH v7 04/22] ARM: mv78xx0: Move to ID based window creation
From: Ezequiel Garcia <hidden>

From: Thomas Petazzoni <redacted> With the introduction of the ID based MBus API, it's better to switch to use it instead of the current name based scheme. This will allow to deprecate the name based API, once every user is removed.
