msm: mdss: update the pp status flags for layermixer 



Post Processing(PP) driver caches the status of the features enabled.
Information is used to turn on the PP features when device is resumed
from suspend state. Currently PP status information is not updated for
layer mixer path. Add support to track the layer mixer status
and prevent programming the DSPP blocks if dirty flag is not set.
