Lucie / minute

found workarounds for 2 major issues on cq8750s:
- gpu (adreno a830) would hang/crash after a few minutes of use, pretty randomly, when GMU is sending the GPU_SET OOB message. this is already a familiar problem to me, but on this platform the cause that i found is pm_autosuspend of the GPU itself. setting the delay to -1 (off) makes the crashes go away and stabilizes the desktop.
- cpu had strangely low performance even at 4GHz. cpuidle=off quadruples the performance!
