lantiq: Configure disabled WLAN bands for TDW89X0.
The TDW8970 has a AR9381, which is the bgn 3x3:3 variant of the AR938x family.
The TDW8980 has a AR9287, which is the bgn 2x2:2 variant of the AR928x family.
This means that the chip for both routers is 2.4 GHz only.
Anyway, the manufacturer didn't disable the 5 GHz band in the EEPROM partition
(at least on my TDW8970).
So this patch disables the 5 GHz band.
