disp: msm: sde: trigger pm_qos vote with irq enable

Browse Source 
Video mode display keeps the MDP clocks in ON state but
disables irq during static screen to avoid cpu wakeup.
In such case, CPU pm_qos vote should also be removed
to allow LPM transition. This change triggers the
pm_qos vote based on mdp interrupt enable counts
instead of runtime_pm callback. It works for
multi-display concurrency also.
