Subject: [PATCH] wifi: rtw89: 8852b: correct TX power controlled by BT-coexistence

When coexistence mechanism is under free-run mode, it could adjust WiFi
and BT TX power to avoid interference with each other. For other cases,
it should keep original TX power from regular predefined tables, so
set correct values to 255 for these cases.
