disp: msm: sde: update sspp multi rect programming

Forráskód böngészése 
Current SDE driver allows staging of rect1 only configuration. When a
real plane is disabled sspp multi rect configuration is not updated.
This can lead to iommu faults and ping pong timeouts as framebuffer of
disabled plane is unmapped. This change fixes it by updating multi rect
config accordingly when a plane is disabled.
