[PATCH ath-next v2 00/17] wifi: ath12k: Add support for QCN6432

[Aaradhana Sahu]

QCN6432 is a PCIe-based device attached to the WCSS Q6 processor. It is
registered as a platform device (AHB), and remoteproc APIs are used to
boot and shut down the device, similar to other AHB-based devices such
as IPQ5332.

However, PCI APIs are used for device setup and register access. Since
QCN6432 requires both AHB and PCI APIs for its operation, a hybrid
AHB/PCI approach is implemented.

Overview:
  - Patch [1/17] adds DT binding documentation for QCN6432.
  - Patch [2/17] refactors PCI operations and MSI config structure to
    support different MSI configurations.
  - Patches [3,4,5/17] add hardware parameters, ring mask, and registers
    for QCN6432.
  - Patch [6/17] moves multi MSI vector flag to ath12k_dev_flags.
  - Patches [7,8/17] add hybrid_bus_type and HIF operations support for
    QCN6432.
  - Patch [9/17] adds support for unified data-region memory allocation.
  - Patch [10/17] moves MSI config to pcic for better abstraction.
  - Patches [11,12/17] enable MSI interrupt support for CE and DP rings
    specific to QCN6432.
  - Patch [13/17] uses CMEM write for PPT on hybrid bus devices.
  - Patch [14/17] stores and uses per CE DP MSI data for QCN6432.
  - Patch [15/17] derives QMI service instance ID per protection domain.
  - Patch [16/17] add userpd ID mapping per device.
  - Patch [17/17] adds support for QCN6432 in the driver.

Changes in v2:
- patch 1/17: Update the compatible string from qcom,qcn6432-wifi to qcom,qcn6432 and remove the | character.
- patch 11/17 and patch 12/17: Fix resource leaks on probe error paths.
- patch 16/17: Move the NULL check before the loop.
