This firmware is useful for other devices (m3, t0lte, p4note, ...), so
let's give it a more generic name and split up WiFi and Bluetooth into
separate packages as the WiFi firmware isn't useful for t0lte at the
moment. Also drop the downstream kernel firmware from here to simplify
the APKBUILD, and give it its own package in the following commit.
With this wifi seem to work reliably, and it is possibly to for
example connect to a bluetooth speaker and play music.
For wifi, issue seem to be with the nvram_net.txt file, changing only
that one to a newer one makes wifi work. Here, both the .txt and .bin
file are updated, as the old files are from 2012, while the new
ones have a datestamp from 2019.
