[PATCH] ramips: fix Gigabit Ethernet port of the HiWiFi HC5861

[Shiji Yang]

From: Shiji Yang <yangshiji66 at qq.com>

HiWiFi HC5861 has a GbE port which connected to the RTL8211E PHY
chip. This patch adds the missing Realtek PHY driver package and
sets the correct external PHYs base address to make it work again.

Hi!

This patch should be backpoted to v22.03 and v23.05 branch. By the
way, I believe a lot of devices need the similar fix. Hope Michael
can have a look.

Thank you!
