Robert Marko 4f592fb819 mac80211: ath11k: hack for multiple card support
This is a temporary workaround for supporting multiple cards or AHB+PCI.

There is ongoing upstream work to properly support this based of
advertised FW features, but that is still ongoing.

This is only supported on QCN9074 cards due to FW limitation, so HW ID
is checked in order to prevent breaking QCA6390 and other popular cards.

Subject: [PATCH] wifi: ath11k: pci: fix compilation in 5.16 and older
Commit ("genirq/msi, treewide: Use a named struct for PCI/MSI attributes")
changed the msi_desc structure a bit, however that is only available in
kernels 5.17 and newer, so check for kernel version to allow compilation
in 5.16 and older.
