[PATCH 0/3] wifi: rtw89: read country list supporting 6 GHz from BIOS

[Ping-Ke Shih]

A platform might get 6 GHz certifications on certain countries, because
many countries still don't allow 6 GHz channels yet. To prevent having
misbehavior on 6 GHz channels, read white or black country list from BIOS
and configure channels accordingly.

Also, update regulatory map to the latest to support more countries for
6 GHz channels.

  wifi: rtw89: regd: handle policy of 6 GHz according to BIOS
  wifi: rtw89: regd: update regulatory map to R65-R44

[PATCH 1/3] wifi: rtw89: acpi: process 6 GHz band policy from DSM

[Ping-Ke Shih]

From: Zong-Zhe Yang <kevin_yang@realtek.com>

Realtek ACPI DSM func 4, RTW89_ACPI_DSM_FUNC_6G_BP,
accepts a configuration via ACPI buffer as below.

| index | description   |
-------------------------
| [0-2] | signature     |
| [3]   | reserved      |
| [4]   | policy mode   |
| [5]   | country count |
| [6-]  | country list  |

Through this function, BIOS can indicate to allow/block
6 GHz on some specific countries. Still, driver should
follow regd first before taking this configuration into
account.

Besides, add a bit in debug mask for ACPI.

[PATCH 2/3] wifi: rtw89: regd: handle policy of 6 GHz according to BIOS

[Ping-Ke Shih]

From: Zong-Zhe Yang <kevin_yang@realtek.com>

According to BIOS configuration of Realtek ACPI DSM function 4,
RTW89_ACPI_DSM_FUNC_6G_BP, we handle the regd policy of 6 GHz.

Policy defines two modes as below.
1. `BLOCK` mode:
    The countries in configured list are blocked.
2. `ALLOW` mode:
    _Only_ the countries in configured list are allowed.
    (i.e. others are all blocked.)

Then, when receiving regulatory notification at runtime, if 6 GHz
is blocked on the country, 6 GHz channels will be disabled.
