Letux-4.8-rc1

Hi, I have merged v4.8-rc1 and fixed conflicts plus some issues: * bme280 driver was not in sync (because we had integrated some earlier patch set) * wl18xx required a firmware upgrade (which seems to be more stable if my 20 minutes test is sufficient...) * some minor API change in touch screen drivers * some of our feature branches are now upstream and have been removed from the merge process * the hw-test script is now much better maintainable (one function for each test) and can not only test the GTA04 but also a lot of Pyra components (e.g. report the IMEI of the 3G/4G module)
