[][openwrt][common][eth][Add a Airoha EN8811H 2.5G PHY driver package]

[Description]
Add a Airoha EN8811H 2.5G PHY driver package.

Airoha recommends using a kernel module to load the EN8811H PHY driver.
If the user does not utilize a kernel module to load the PHY driver,
the PHY driver may have failed to download the firmware.

Without this patch, the PHY driver may not download the firmware
successfully.
