wifi: rtw89: chan: re-calculate MLO DBCC mode during setting channel
Wi-Fi 7 chips have dual HW bands. After impending MLO support, they
can work with HW-[0] / HW-[1] / HW-[0,1] according to active links.
So, during setting channel, also re-calculate the MLO DBCC mode flag.
Then, leaf chip functions of setting channel can configure with HWs
based on current case.
Besides, tweak the initial and idle MLO DBCC mode of Wi-Fi 7 chips to
MLO_1_PLUS_1_1RF to work with dual HW bands. And, after disconnecting,
due to no active links, MLO DBCC mode will re-calculate to idle case,
i.e. MLO_1_PLUS_1_1RF.
