disp: msm: sde: reset plane cache state on plane disable

Browse Source 
Plane cache state is updated based on the crtc's cache state.
The plane is left with state cache state, if the particular plane
is not used in the subsequent frame by the same crtc. Reset the
plane cache state on plane disable and reset_custom_properties to
avoid this case.
