According to the schematics of the S400 v3, only I2SB_DIN3 and
I2SC_DOUT2 will be available to the speaker board.

9R83, 9R84 and 9R18 are not connected so no audio signal will be
provided to the second amplifier. There is no point in enabling it
even if it is visible on the i2c bus.

ARM64: dts: meson-axg: fix ethernet stability issue

Like the odroid-c2 and wetek, the s400 uses the RTL8211F and seems to
suffer from the kind of stability issue.

Doing an iperf3 download test, we can see a significant number of LPI
interrupts on the tx path. After a short while (5 to 15 seconds), the
network connection dies. If using rootfs over NFS, the connection may
also break during the boot sequence.

We still don't have a real explanation for this problem so let's disable
EEE once again.
