Subject: [PATCH v5 7/8] [DNI] arm64: dts: renesas: salvator-x-max9286: Specify channel amplitude

Use the newly introduced 'maxim,initial-reverse-channel-mV'
property to specify the initial reverse channel amplitude when
the remote serializers are pre-programmed with noise immunity threshold
enabled.
