wifi: ath12k: introduce mlo_capable flag for device group

Currently, during mac80211 allocate and register single device is
considered for the registration. But, in future, during multi device
group abstraction is introduced, all the devices has to be combined
together as a single abstraction and then hardware should be allocated.

All the devices in the group should be combined together only if it
supports inter device mlo capability. The decision of whether to combine
the devices or not can be based on the mlo capability flag in
ath12k_hw_group.

By default, mlo_capable flag in the group would be set as false. During
QMI PHY capability exchange, only when we have more than one chip in the
group or if one chip, then that chip supports inter MLO, then mlo_capable
flag in the group will be enabled.

Add changes to introduce mlo_capable flag for device group and refactor
ath12k_mac_hw_allocate() api based on device group (ag) rather than
device (ab).
