====================
mlxsw: Extend device registers for line cards support

This patch set prepares mlxsw for line cards support by extending device
registers with a slot index, which allows accessing components found on
a line card at a given slot. Currently, only slot index 0 (main board)
is used.

No user visible changes that I am aware of.
