eMMC HS200 mode (1.8V I/O) is supported by the MMC host controller on
RK3528 and works with the optional on-board eMMC module on Radxa E20C.
Be explicit about HS200 support in the device tree for Radxa E20C.

Even though they will be the same for all boards, i2c and uart aliases
are supposed to live in the individual board files, to not create
aliases for disabled nodes.
So move the newly added aliases for rk3528 over to the Radxa E20C board,
which is the only rk3528 board right now.

The Radxa E20C has two GbE ports, LAN and WAN. The LAN port is provided
using a GMAC controller and a YT8531C PHY and the WAN port is provided
by an RTL8111H PCIe Ethernet controller.
Enable support for the LAN port on Radxa E20C.
