chore: modify BQ device as adb+mtp, or mtp

initial patch was to add android links, however, based on looking at
libmtp these are both mtp, therefore changed these to adb+mtp, while
the mtp-only product was dropped and left for libmtp to handle since
it appears there is no adb for this. More details given in issue M0Rf30#46
