disp: msm: sde: fix compression info usage in resource alloc

Browse Source 
Currently, compression info passed to resource manager is not
valid in atomic check phase. Also in current design allocation
of msm mode info object is from stack which is huge and causing
stack overflow in continuous splash use case. This change fixes
these issues by moving mode info object to heap allocation.
