RDMA/mlx5: Add support in MEMIC operations
MEMIC buffer, in addition to regular read and write operations, can
support atomic operations from the host.

RDMA/mlx5: Add support in MEMIC operations
MEMIC buffer, in addition to regular read and write operations, can
support atomic operations from the host.
Introduce and implement new UAPI to allocate address space for MEMIC
operations such as atomic. This includes:
1. Expose new IOCTL for request mapping of MEMIC operation.
2. Hold the operations address in a list, so same operation to same DM
will be allocated only once.
3. Manage refcount on the mlx5_ib_dm object, so it would be keep valid
until all addresses were unmapped.

RDMA/mlx5: Re-organize the DM code
1. Inline the checks from check_dm_type_support() into their

RDMA/mlx5: Re-organize the DM code
1. Inline the checks from check_dm_type_support() into their
respective allocation functions.
2. Fix use after free when driver fails to copy the MEMIC address to the
user by moving the allocation code into their respective functions,
hence we avoid the explicit call to free the DM in the error flow.
3. Split mlx5_ib_dm struct to memic and icm proper typesafety
throughout.
