turris: get slot name from label instead of port id

Read of_node/label instead of phys_switch_id and don't try to concat port label by lan + port_id.

Besides that, it will fix discrepancies between phys_switch_id and port label on Turris 1.x, in which case they are opposite of each other, for instance:

• LAN1 <-> port 4 <-> lan5
• [...]
• LAN5 <-> port 0 <-> lan1

Closes: turris/reforis/reforis#364 (closed)

Note: Refactoring of code for Mox and Omnia is intentionally postponed, because detection and reporting interfaces hasn't changed for quite a long time and the current state is considered as expected behavior -at least from user point of view ;-)
