msm: mdss: Fix apq8084 compilation failure due to large struct size

Browse source 
Due to overlay struct size increase, the stack size requirement
for function is increasing when it is used as local variable.
This causes the compilation failure due to fix stack size on
APQ8084. This change fixes the issue by using overlay structure
from heap instead of stack.
