Introduce a new macro MLXSW_RXL_DIS that allows to register listeners
as disabled. That allows that from now on, the "action" can be
understood always as "enabled action" and "unreg_action" as "disabled
action". Rename them and treat them accordingly.

Use the new macro for defining drops in spectrum_trap.c.

Currently it does not really matter if it is set to DISCARD or
SET_FW_DEFAULT because it is set only during unregister of the listener.
The unreg_action is going to be used for disabling the listener too, so
change to SET_FW_DEFAULT and ensure the HW is going to behave correctly.

====================
Clean driver, module and FW versions

Change log:
 v1:
  * Split all FW cleanups patches to separate patches
  * Fixed commit message
  * Deleted odd DRV_RELDATE
  * Added everyone from MAINTAINERS file
 v0: https://lore.kernel.org/netdev/20200220145855.255704-1-leon@kernel.org

This is first patchset to netdev (already sent RDMA [1] and arch/um [2])
in attempt to unify the version management for in-tree kernel code.
The patches follow already accepted ethtool change [3] to set as
a default linux kernel version.

It allows us to remove driver version and present to the users unified
picture of driver version, which is similar to default MODULE_VERSION().

As part of this series, I deleted various creative attempts to mark
absence of FW. There is no need to set "N/A" in ethtool ->fw_version
field and it is enough to do not set it.

1.
The code is compile tested and passes 0-day kbuild.
2.
The proposed changes are based on commit:
  2bb07f4e ("tc-testing: updated tdc tests for basic filter")
3.
WIP branch is [4].
