mediatek: EX5601-T0 add Zyxel EX5601-T1 and T-56 alias

Define EX5601-T1 and T-56 as alternative name, to explicitly show
the device is supported using existing image. EX5601-T1 does not
have the option to switch between WAN/SFP port. The switch port
is hardwired to the WAN port. The Zyxel T-56 is the odido-branded
version of the EX5601-T1.
