ath79: disable TP-Link TL-WR941ND v2

The support for this device's Marvell MV88E6060 switch has been
reported to be broken with kernels 4.19/5.4 (see bug report).

Since this a 4/32 device and it has been confirmed to be working
with stable 19.07 release (kernel 4.14), and since fixing it does
not seem trivial, let's just disable it in master.

Fixes: FS#2524
