[PATCH v3 01/10] wifi: ath12k: change interface combination for P2P mode

[Kang Yang <quic_kangyang@xxxxxxxxxxx>]

Current interface combination doesn't support P2P mode. Change the
combination for P2P mode.

Also, there is a bug that when mesh is enabled but ap is not enabled.
In this situation, the mesh's max_interface of interface combination
won't be set.

So assign the max_interfaces for mesh directly.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

Signed-off-by: Kang Yang <quic_kangyang@xxxxxxxxxxx>

v3: rebase on new ath-tag.
v2: 
    1. add Tested-on tag of QCN9274.
    2. update copyright.
