The H616 secondary EMAC supports RMII at 10/100 Mbps and uses a separate
system-control clock register at offset 0x34. Add its binding and a
sun8i stmmac variant using that register. A distinct compatible without
an older fallback prevents the driver from using EMAC0's clock register.

The PHY commonly connected to EMAC1 is in an AC200 or AC300 companion
package, not the H616 die. Leave its initialization to the PHY driver
instead of using the H3 internal-PHY controls. Retain the supported TX
and RX delay settings through the shared syscon setup.

The AC200/AC300 EPHY driver and package bindings are already in
net-next. This series separates the H616 EMAC1 MAC driver and binding
support from the earlier combined series. PWM, MFD and device-tree
enablement are being handled separately.
