disp: msm: sde: set top left coordinates for noise and attenuation layers

Noise and attenuation layers are full screen layers. Top left coordinates
are not cleared in some use cases when same blend stage is assigned to
noise and attenuation layers. This change sets top left coordinates of noise
and attenuation layers.
