Merge branch 'mlx5-next' of git://git./linux/kernel/git/mellanox/linux

This merge commit includes some misc shared code updates from mlx5-next branch needed
for net-next.

1) From Maxim, Remove un-used macros and spinlock from mlx5 code.

2) From Aya, Expose Management PCIE info register layout and add rate limit
print macros.

3) From Tariq, Compilation warning fix in fs_core.c

4) From Vu, Huy and Saeed, Improve mlx5 initialization flow:
The goal is to provide a better logical separation of mlx5 core
device initialization flow and will help to seamlessly support
creating different mlx5 device types such as PF, VF and SF
mlx5 sub-function virtual devices.

Mlx5_core driver needs to separate HCA resources from pci resources.
Its initialize/load/unload will be broken into stages:
1. Initialize common data structures
2. Setup function which initializes pci resources (for PF/VF)
   or some other specific resources for virtual device
3. Initialize software objects according to hardware capabilities
4. Load all mlx5_core components

It is also necessary to detach mlx5_core mdev name/message from pci
device mdev->pdev name/message for a clearer report/debug of
different mlx5 device types.
