[PATCH ath-next 15/16] wifi: ath11k: define userPDs for QCN6122

[George Moussalem via B4 Relay]

From: George Moussalem <george.moussalem@xxxxxxxxxxx>

The IPQ5018 platform can come with one or two optional QCN6122 wifi
cards. To differentiate the two, the user PD instance number (1 or 2) is
added to the QMI service instance ID so the QCN6122 firmware knows which
radio instance to use and on what PCIe rail it is on.

On IPQ5018/QCN6122 boards, the default mapping is as follows:

          +-> User PD 1 ----> IPQ5018 Internal 2.4G Radio
         /
        /
Root PD +---> User PD 2 ----> QCN6122 5G/6G Radio on PCIe rail 1
        \
         \
          +-> User PD 3 ----> QCN6122 5G/6G Radio on PCIe rail 0
