disp: msm: sde: adapt VM IRQ notification framework

Kernel RM IRQ wrapper has changed the prototype of the
notification callback function to support per event
notifications. This uncouples the VM IRQ operations from
their respective notifications.

Adapt the changes in SDE driver by making the notification
handler generic and invoking the notifications calls
explicitly.
