Subject: [PATCH v3 0/5] Refactor PCI code to support WCN6750

Unlike other ATH11K PCIe devices which are enumerated by APSS
processor (Application Processor SubSystem), WCN6750 gets
enumerated by the WPSS Q6 processor (Wireless Processor SubSystem);
In simple terms, though WCN6750 is PCIe device, it is not attached
to the APSS processor, APSS will not know of such a device being
present in the system and therefore WCN6750 will be registered as
a platform device to the kernel core like other supported AHB
devices.

WCN6750 needs both AHB and PCI APIs for it's operation, it uses
AHB APIs for device probe/boot and PCI APIs for device setup and
register accesses. Because of this nature, it is referred as a
hybrid bus device.

Refactor PCI code to support hybrid bus devices like WCN6750.

Manikanta Pubbisetty (5):
  ath11k: PCI changes to support WCN6750
  ath11k: Refactor PCI code to support WCN6750
  ath11k: Choose MSI config based on HW revision
  ath11k: Refactor MSI logic to support WCN6750
  ath11k: Remove core PCI references from PCI common code

V3:
 - Patch series with 19 patches is split in 2 patch series, this is the first one
 - Rebased on ToT SHAID: 7316a74e54318d0cd648242b18ea83cdef6dda96
 - Changed the PCI common code file name from pci_cmn.* to pcic.*
 - Added ath11k_pcic_* prefix to all APIs in PCI common code
 - Added pci_ops instead of having the chip specific PCI ops in bus_params

V2:
 - Rebased on ToT
