boards/nrf52: cleanup shared Makefile.deps

[haukepetersen]

Contribution description

The nrf52832 and the nrf52840-based platforms have different default radio modes (nimble_netif and nrf802154, respectively). But the according Makefile.deps were a little messy, so this PR should improve on this...

Testing procedure

For gnrc_networking, verify that all nrf52840 boards are now being build with the 802.15.4 support (nrf802154) and all nrf52832 baords with IP-over-BLE support (nimble_netif). Also, all boards should flawlessly build with nrfmin.

Just in case someone is wondering: for some reason, some of the effected boards were per default using the nrfmin driver. Although this is/was helpful for including this driver in the build tests, it is quite strange to have some boards using this driver, and some others with the same CPU using another radio mode... I opened an issue for including the nrfmin driver again in the build tests (#12115), so we don't forget about this.

Could this be considered as a duplicate of #11792 ? (I haven't look into the details).

[haukepetersen]

Just noticed: this PR also fixes all nrf52840 boards, as currently we are not able to build nimble_netif for these due to a collision with the nrf802154 module...

[haukepetersen]

yes, it actually is kind of (did not see it...). Although #11792 has still some dependency loop and it is not up-to-date with the ble stuff we merged yesterday.

I don't care how we proceed, do you want to adapt #11792 and I simply close this PR? Or the other way around?

closing in favor of #11792
