Updates to allow Intenic-8 tablet to boot Kit-Kat PDK.

1. added option --no-module to pvrsrvctl instead of relying
   on a hack in the program which is being removed.

2. make /dev/pvr_sync permissions 666. Needed for new
   fence sync code in surface flinger to work.

3. Disabling camera code for now.

4. Updated kernel to one supporting the tentative IMG PVR DDK 1.12.
   This has an update to support the Android Kit-Kat PDK and
   is based on prior IMG PVR DDK 1.10-RC and 1.11 RC releases.
