Add support for Ciseco SRF-Stick

[ecc1]

I added support for another CC1111 dongle from Ciseco (now Wireless Things): https://www.wirelessthings.net/srf-stick-868-915-mhz-easy-to-use-usb-radio

But it's only marginally useful because this dongle does not have a pushbutton to force it into bootloader mode.

Also, I made up USB product IDs (ecc0 and ecc1 :-) without requesting them through OpenMoko, mea culpa.
