wifi: ath12k: reset MLO global memory during recovery

When operating with multiple devices grouped together, the firmware stores
data related to the state machine of each partner device in the MLO global
memory region. If the firmware crashes, it updates the state to 'crashed'.
During recovery, this memory is shared with the firmware again, and upon
detecting the 'crashed' state, it reasserts. This leads to a loop of
firmware asserts and it never recovers.

Hence to fix this issue,  once all devices in the group have been asserted
and powered down, reset the MLO global memory region.
