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

[Marcos Alano]

> 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 work because of this outdated rule based on an outdated normative.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,

Hi, I created a patch to solve that.

Subject: [PATCH] wireless-regdb: Update regulatory rules for Brazil (BR) on
  6GHz

Change rules for 6GHz in Brazil, removing `NO-IR` and adding
`AUTO-BW` so the 6GHz band can be used.

Add the relevant normative in comments.
