In previous mechanism, p2p channel only can raise on same channel
while STA connected to 2.4GHz band. However, if device support DBS
mode, we should allow p2p to raise on 5GHz band for 230423673 higher
performance.
Bug: 272687278
Test: connect STA to 2.4GHz and verified that p2p is able to come up in
5GHz DBS mode.
