mlx5_core: Implement new initialization sequence
Introduce enbale_hca and disable_hca commands to signify when the driver starts or ceases to operate on the device. In addition the driver will use boot and init pages count; boot pages is required to allow firmware to complete boot commands and the other to complete init hca. Command interface revision is bumped to 4 to enforce using supported firmware. This patch breaks compatibility with old versions of firmware (< 4); however, the first GA firmware we will publish will support version 4 so this should not be a problem.
