arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins
The EthernetAVB should not depend on the bootloader to setup correct drive-strength values. Values for drive-strength where found by examining the registers after the bootloader has configured the registers and successfully used the EthernetAVB.
