dt-bindings: pse: tps23881: Clarify channels property description

Browse Source 
Improve the channels property description to better explain the
relationship between physical delivery channels and PSE PI pairsets.
The previous description was unclear about how channels are referenced
and used in the port matrix mapping.

description: each set of 8 ports can be assigned to one physical
channels or two for PoE4. This parameter describes the configuration
of the ports conversion matrix that establishes relationship between
the logical ports and the physical channels.
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.
