Merge branch 'mlx5-next'

Eli Cohen says:

====================
mlx5 driver changes related to PCI handling ***

The first of these patches is changing the pci device driver from mlx5_ib to
mlx5_core in a similar manner it is done in mlx4. This set the grounds for us
to introduce Ethernet driver for HW which uses mlx5.

The other two patches contain minor fixes.
