atomisp: [REVERTME] request minimum CPU wakeup latency

BZ: 34648

CLV+ drivers put idle system into a low-performance mode which
causes ISP interrupts to disappear. This leads to ISP timeout errors
under light load. Fix the issue by requesting lowest wakeup latency
from pm_qos subsystem.

This is a temporary solution; the root cause should be still
investigated.
