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.

will prevent that CPU from going into low power mode avoiding

receive notification when display IRQ has switched CPUs and
will adjust the vote accordingly. The vote is also removed and
requested whenever display IRQ is enabled or disabled.

In Dual display concurrencies there are certain cases where
irq_idx and vblank_refcount state mismatch can occur.
To avoid it, during setup of irq_hw_idx, reset the vblank_refcount
and unregister read ptr irq if not yet done by then along with
maintaining global mutex lock for vblank_refcount.
Also, if register IRQ fails, correct vblank_refcount so
that IRQ registration can be tried again.
