disp: msm: sde: reset dim layer dirty prop during idle pc

Browse Source 
During idle power collapse, dim layer dirty flags are
stored in sde_crtc_state which might be invalid if state
swap occurs. This change adds revalidate mask in sde_crtc
structure to revalidate after coming out of idle power
collapse.
