[LEDE-DEV] [PATCH] ramips: Improve Sanlinking D240 config

[Kristian Evensen]

* The left most mini-PCIe (USB) slot (the one attached to SIM2) can be
power-cycled by setting GPIO 0 to high/low. I have no strong opinion on the
name, but since the slot can be used for other things than modems I went for
usb2.

* The D240 only needs the MT76x2 module, so update makefile to reflect this.
Note that until the default mt7620 target is updated, then kmod-mt76 (and thus
kmod-mt7603) will be selected by default.
