msm: mdss: Add extra panel info element in the fb_data_type

Browse source 
Dynamically allocating memory and using can cause overhead
while the memory is getting allocated and de-allocated for
every update for recovery use-cases. Hence, add one more
instance of struct panel info element in the fb_data_type
and use it.
