gpu: ion: Add flag for forcing contiguous allocations

Browse Source 
Previously, a parameter was added to secure heaps to only
allow secure allocations. Some clients still require
non-secure contiguous allocations even though the SMMU is
supported. Add support for those clients to force contiguous
allocations to go through.
