mlx5: Support communicating arbitrary host page size to firmware
Connect-IB firmware requires 4K pages to be communicated with the driver. This patch breaks larger pages to 4K units to enable support for architectures utilizing larger page size, such as PowerPC. This patch also fixes several places that referred to PAGE_SHIFT instead of explicit 12 which is the inherent page shift on Connect-IB.
