boards: cc1352r1_launchxl / cc26x2r1_launchxl: add BoosterPack connector

Add BoosterPack connector information to the DTS of the CC1352 and
CC26x2 LaunchPad boards. This allows shields (e.g. BoosterPacks) to use
aliases for the connector interfaces and mappings for the GPIOs. This is
similar to what is being done for the Arduino connectors.
