octeon_ep: Add control plane host and firmware versions. Implement control plane mailbox versions for host and firmware. Versions are published in info area of control mailbox bar4 memory structure.Firmware will publish minimum and maximum supported versions.Control plane mailbox apis will check for firmware version before sending any control commands to firmware. Notifications from firmware will similarly be checked for host version compatibility. Signed-off-by: Sathesh Edara <sedara@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

octeon_ep: initialize mbox mutexes The two mbox-related mutexes are destroyed in octep_ctrl_mbox_uninit(), but the corresponding mutex_init calls were missing. A "DEBUG_LOCKS_WARN_ON(lock->magic != lock)" warning was emitted with CONFIG_DEBUG_MUTEXES on. Initialize the two mutexes in octep_ctrl_mbox_init().

octeon_ep: Remove custom driver version In review comment [1] was pointed that new code is not supposed to set driver version and should rely on kernel version instead. As an outcome of that comment all the dance around setting such driver version to FW should be removed too, because in upstream kernel whole driver will have same version so read/write from/to FW will give same result.
