====================
mlxsw: Add support for transceiver modules reset

This patchset prepares mlxsw for future transceiver modules related [1]
changes and adds reset support via the existing 'ETHTOOL_RESET'
interface.

Patches #1-#6 are relatively straightforward preparations.

Patch #7 tracks the number of logical ports that are mapped to the
transceiver module and the number of logical ports using it that are
administratively up. Needed for both reset support and power mode policy
support.

Patches #8-#9 add required fields in device registers.

Patch #10 implements support for ethtool_ops::reset in order to reset
transceiver modules.
