drm/amd/display: Add the MALL size in the fallback function

Browse Source 
[Why & How]
If the driver has issues retrieving the MALL size for the specific
hardware, it might fail since the current value is set to zero. This
commit addresses this issue by adding a simple constant value to give
the drive a chance to start.
