wireless-regdb: Update regulatory rules for Brazil (BR) on 6GHz

Hi,

The rules for Brazil were based on this normative 
https://informacoes.anatel.gov.br/legislacao/resolucoes/2017/936-resolucao-680, 
as mentioned in the comments of the entry.

This January came out a newer normative 
https://informacoes.anatel.gov.br/legislacao/resolucoes/2025/2001-resolucao-772,

It allows 6GHz frequencies, so the line:
(5925 - 7125 @ 320), (12), NO-OUTDOOR, NO-IR
Should change for, at least:
(5925 - 7125 @ 320), (12), NO-OUTDOOR
The removal of NO-IR is important, since routers Wi-Fi 6E and 7 don't 
work because of this outdated rule based on an outdated normative.

I'm no lawyer, so please if you see something different, like more 
granular control in the allowed frequencies, please let us know.

Thanks,
