Ics 3.0

Hi Arne,
the following two commits included with the pull request on cm-10.1_3.0 branch don't need to be applied on ics-3.0 branch (due to different autobrightness driver):
- set the DEFAULT_GAMMA_LEVEL from 160CD to 20CD 	e67f8aa
- video: msm: lcdc_s6e63m0: Corrected an unmanaged gamma for autobrightess 	5c8865a 

Thank you.
Regards.
