mlx5: Move pci device handling from mlx5_ib to mlx5_core

In preparation for a new mlx5 device which is VPI (i.e., ports can be either IB or ETH), move the pci device functionality from mlx5_ib to mlx5_core. This involves the following changes: 1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev is now an independent structure maintained by mlx5_core. mlx5_ib_dev now has a pointer to that struct. This requires changing a lot of places where the core_dev struct was accessed via mlx5_ib_dev (now, this needs to be a pointer dereference). 2. All PCI initializations are now done in mlx5_core. Thus, it is now mlx5_core which does pci_register_device (and not mlx5_ib, as was previously). 3. mlx5_ib now registers itself with mlx5_core as an "interface" driver. This is very similar to the mechanism employed for the mlx4 (ConnectX) driver. Once the HCA is initialized (by mlx5_core), it invokes the interface drivers to do their initializations. 4. There is a new event handler which the core registers: mlx5_core_event(). This event handler invokes the event handlers registered by the interfaces.
