Convert the legacy txt binding to modern YAML and rename from
client-devices to hsi-client. No semantic change.

-Each HSI port is supposed to have one child node, which

-following properties are standardized for HSI clients:
-
-Required HSI configuration properties:
-
-- hsi-channel-ids: A list of channel ids
-
-- hsi-rx-mode: Receiver Bit transmission mode ("stream" or "frame")
-- hsi-tx-mode: Transmitter Bit transmission mode ("stream" or "frame")
-- hsi-mode: May be used instead hsi-rx-mode and hsi-tx-mode if
- the transmission mode is the same for receiver and
- transmitter
-- hsi-speed-kbps: Max bit transmission speed in kbit/s
-- hsi-flow: RX flow type ("synchronized" or "pipeline")
-- hsi-arb-mode: Arbitration mode for TX frame ("round-robin", "priority")
-
-Optional HSI configuration properties:
-
-- hsi-channel-names: A list with one name per channel specified in the
- hsi-channel-ids property
-

-Device Tree node example for an HSI client:
