disp: msm: sde: update framedata event handling

Browse Source 
This change updates framedata event and ubwc stats API to
align with userspace handling and expectations.

This change adds the empty irq event handler required to register
the frame data event.

This change also adds handling to the crtc event notify to provide
the payload pointer directly, required for the buffer object,
ensuring pointers are not mismatched while sending drm events.

This change also updates the ubwc roi plane property to process the
uapi defined roi.
