Aligned with what we have done for the others nodes. It will also allow
to easily modify the cpu configuration at board (or sub-SoC) level.

This patch adds CPU deep Idle and Cluster deep Idle states BUT it defines
the idle state for each cpu (defined under cpu-idle-states parameter)
only for the quad version therefore it does NOT activate CPU Idle
capability for the other version.
