Lukasz Majewski March 4, 2014, 10:27 a.m. UTC 
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
