Change rules for 6GHz on Brazil removing `NO-IR` and adding
`AUTO-BW` so the 6GHz band can be used.
AUTO-BW is not needed since there are no adjacent bands that can be
combined.
Add the relevant normatives in comments.

Also, the 12 dBm power limit is warranted by the PSD limit of -1 dBm / MHz.
At the smallest 20 MHz channel width, that converts to around 12 dBm.
You can see here:
https://informacoes.anatel.gov.br/legislacao/atos-de-requisitos-tecnicos-de-gestao-do-espectro/2024/1920-ato-915,
in the items IX.4 IX.5 from table IX, that the maximum allowed dBm is 38dBm.
That seems to align with the 40GHz range, where the maximum dBm is 40,
but it's up to you.
