### Contribution description
Taken from #7107 by @gebart: 
> This is the radio found in NXP Kinetis KW41Z, KW21Z. Only 802.15.4 mode
> is implemented (KW41Z also supports BLE on the same transceiver).
> The driver uses vendor supplied initialization code for the low level
> XCVR hardware, these files were imported from mcuxpresso.nxp.com (KSDK 2.2.0, framework_5.3.5)
> The reason for using the vendor code is that setting up the XCVR module requires a lot of precalculated values which I don't have time to recreate. The vendor code works and was imported with minimal modifications to support easy updates if a new version comes out.
> Tested with two FRDM-KW41Z boards running gnrc_networking example

Since #7107 I fixed the known bugs that were reported there and I've used it extensively for months. By now I think it's getting to be a pretty mature radio driver.

### Testing procedure
Confirm `gnrc_networking` example works as intended.

### Issues/PRs references
Taken from #7107. Compatible with (but does not depend on) #11789.
