> Allows flahsing CCFG configuration using Kconfig,
formely "make menuconfig".
> Supports cc26x0, cc26x2_cc13x2.
> Can be used to enable bootloader backdoor, to use
cc2538-bsl flashing script.
> Not all options are in Kconfig, most important ones,
others can be added in further commits.
> On cc13xx targets the VDDR high option can be enabled
using Kconfig.
> With this, RIOT can flash blank chips and the firmware
will run just fine.
