The LogicPD Torpedo DM3730 devkit consists of a base board and two processor boards. One of the processor boards has a WLAN and the other one does not. Let's set up basic dts file so we can move to device tree only based booting over next few merge windows. So far I've tested that UARTs, MMC1, USB OTG, smsc911x, and basic PM support works. Note that the wireless support in kernel for wl1283 seems to be broken, it tries to load wl127x-nvs.bin instead of wl128x-nvs.bin with firmware.
