There is only 1 global var to save EHT cap in psoc cfg for both 2 GHz and
5 GHz band, it is propagated to vdev/pe session/frames without revising by
band, so EHT cap of 2 GHz and 5 GHz are same, EHT cap of assoc link and
partner link are same, so no EHT cap in ML-Link Info(per STA Profile) in
assoc request while connecting to EHT MLO AP.
To fix it, revise EHT cap when band is selected, get EHT cap by band when
assemble assoc req MLO link per sta profile, get correct 2 GHz cap by
checking supported bands when get MAC/PHY cap from firmware, copy supported
MCS set from firmware to EHT cap of 2 GHz and 5 GHz too.
