Allow loading of larger images than 512 MB by dropping the arbitrary hard-coded value that we have today and move to use the max device loading value which is for now 4GB. As part of that we move to use the GFP_KERNEL_ACCOUNT option upon allocating the persistent data of mlx5 and rely on the cgroup to provide the memory limit for the given user. The GFP_KERNEL_ACCOUNT option lets the memory allocator know that this is untrusted allocation triggered from userspace and should be a subject of kmem accounting, and as such it is controlled by the cgroup mechanism.
