/**
* @brief Creates an object that manages allocating OS memory
*
* Creates an object that provides an interface to allocate OS memory and
* have it mapped into the Mali virtual memory space.
*
* The object exposes pointers to
* - allocate OS memory
* - allocate Mali page tables in OS memory
* - destroy the object
*
* Allocations from OS memory are of type mali_physical_memory_allocation
* which provides a function to release the allocation.
*
* @param max_allocation max. number of bytes that can be allocated from OS memory
* @param cpu_usage_adjust value to add to mali physical addresses to obtain CPU physical addresses
* @param name description of the allocator
* @return pointer to mali_physical_memory_allocator object. NULL on failure.
