mediatek: add Motorcomm PHY support to Cudy AP3000 v1

Browse source 
Newer Cudy AP3000 v1 routers feature a Motorcomm YT8821 PHY
instead of the Realtek PHY [1]. Support for the YT8821
was recently introduced for the Cudy WR3000H router [2].
On the AP3000, the changes allow the PHY to be autodetected.
