wifi: iwlwifi: cfg: clean up Sc/Dr/Br configs

For now, the WH and PE radios require the same config as
FM, so just add a #define for those instead of copying
the data. Since this is true, Sc/Dr/Br all used the same
configs for all RF types, but that's confusing, so now
use the defined WH/PE names for the correct combinations.

We can also now enable the unit test that ensures we have
no duplicate RF configs.
