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.

The IP of eMMC controller in AXG is similiar to Meson-GX series.
Here we add the initial support of the HS200 mode with
clock running at 166MHz (to be safe), since we found some eMMC chip
fail to run at 200MHz due to tunning phase error.
