Add Airoha AN8855 5-Port Gigabit DSA switch. Switch can support
10M, 100M, 1Gb, 2.5G and 5G Ethernet Speed but 5G is currently error out
as it's not currently supported as requires additional configuration for
the PCS.
The switch is also a nvmem-provider as it does have EFUSE to calibrate
the internal PHYs.

I don't think this can happen. So it could be removed?
