Adds LAB attributes to proper CPU0 node.
The lab-num-of-states attribute shows how many compartments will be used.
The LAB code is prepared to be more fine grained.
The lab-ctrl-freq defines how the LAB governor will be controlled:
- 0xFFFFFFFE - use the minimal frequency
- 0xFFFFFFFF - enable boost
- non zero - set the frequency specified
- zero - use ondemand to specify output frequency
