The database supports one rule per frequency range.

You can write it as two ranges, and add AUTO-BW to both. The kernel
will see this and know that the two bands can be combined. That way
if someone is using a smaller channel width that fits into the lower
band, they can use a higher power limit. This is what we do for the
5 GHz bands that have varying requirements.
