powerpc/4xx: Add Canyonlands suspend and idle support
- Add Clock Power Management (CPM) node to dts tree - Add idle-doze entry in CPM node - Add standby entry in CPM node - Add PM and SUSPEND support by default in defconfig - Remove UART2 and UART3 as they are unused, this will allow CPM to put unused-units (UART2 and UART3) to sleep.
