Finally added all packages to kernel and build correctly. Also load correctly:

[  162.361441] ath11k_pci 0000:01:00.0: assign IRQ: got 0
[  162.366922] ath11k_pci 0000:01:00.0: BAR 0: assigned [mem
0x20000000-0x20ffffff 64bit]
[  162.380001] ath11k_pci 0000:01:00.0: enabling device (0000 -> 0002)
[  162.386358] ath11k_pci 0000:01:00.0: enabling bus mastering
[  162.392043] ath11k_pci 0000:01:00.0: failed to get 32 MSI vectors,
only -28 available
[  162.399927] ath11k_pci 0000:01:00.0: failed to enable msi: -28
[  162.405778] ath11k_pci 0000:01:00.0: disabling bus mastering
[  162.411481] ath11k_pci: probe of 0000:01:00.0 failed with error -28

Seems other ath11k patch will be required, while MSI failed to get 32 vectors
