arm64: dts: r8a7795: salvator-x: Set drive-strength for ravb pins

Browse Source 
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.
