dt-bindings: PCI: toshiba,tc9563: Restrict Tx Amplitude, DFE and N_FTS to USP, DSP1 and DSP2
TC9563 switch allows configuring Tx Amplitude, DFE and N_FTS settings only
to USP, DSP1 and DSP2 ports. These settings don't apply to DSP3 or the
integrated Ethernet MAC Endpoint.
Restrict these properties and move 'toshiba,tx-amplitude-microvolt' to DSP2
in the example to conform to the binding.
