wifi: rtw89: add mlo_dbcc_mode for WiFi 7 chips
WiFi 7 chips can operate in various MLO applications, such as 1 link (2SS)
and 2 links (1SS + 1SS), and we should configure different PHY mode for
each of them.
For example,
- MLO_2_PLUS_0_1RF is 1 link with 2SS rate, and enable one RF component.
- MLO_1_PLUS_1_1RF is 2 links with 1SS rate for each, and enable one RF
component that can support two paths.
By default, we set the mode to legacy MLO_DBCC_NOT_SUPPORT (don't support
MLO and DBCC yet), and later we will introduce logic to change the mode.
