Add the TPS23881B I2C power sourcing equipment controller to the list of supported devices. Falling back to the TPS23881 predecessor device is not suitable as firmware loading needs to handled differently by the driver. The TPS23881 and TPS23881B devices require different firmware. Trying to load the TPS23881 firmware on a TPS23881B device fails and must therefore be omitted.

description: |
|
|
Defines the 8 physical delivery channels on the controller that can
|
|
be referenced by PSE PIs through their "pairsets" property. The actual
|
|
port matrix mapping is created when PSE PIs reference these channels in
|
|
their pairsets. For 4-pair operation, two channels from the same group
|
|
(0-3 or 4-7) must be referenced by a single PSE PI.
