[PATCH v8 0/4] wifi: ath12k: ACPI support

[Kalle Valo <kvalo@kernel.org>]

From: Kalle Valo <quic_kvalo@quicinc.com>

Through reading ACPI tables, implement Time-Average-SAR(TAS), BIOS SAR,
configuration of CCA threshold and band edge channel power functionalities.
This is enabled only on WCN7850.

TODO:

* test with ACPI support in hardware (I don't have such hardware), especially
  suspend and hibernation

v8:

* rebase to ath-202404181528
* rewrite commit messages
* cleanup and improvements all over to match the ath12k style, including
  error handling, naming and so on
* locate new place to call ath12k_acpi_[start|stop]()
* move wmi functions up in wmi.c file
* consolidate WMI functions using WMI_PDEV_SET_BIOS_INTERFACE_CMDID into ath12k_wmi_set_bios_cmd()
* ath12k_acpi_stop(): don't call acpi_remove_notify_handler() if we never installed the handler

v7: https://patchwork.kernel.org/project/linux-wireless/cover/20231013114434.81648-1-quic_lingbok@quicinc.com/

* adjust the length of line
* add cpu_to_le32()

v6:

* remove code that is not called

v5:

* rebase to the latest tag

v4:

* revise commit log using imperative voice
* delete guid_is_null()

v3:

* remove unnecessary cpu_to_le32()
* adjust the order of the macros
* apply jeff's advice

v2:

* put <linux/acpi.h> in the include guard
