Currently, ath12k does not have the ability to set band edge channel power
for WCN7850. In order to support this, ath12k gets band edge channel power
table in ath12k_acpi_dsm_get_data() function and sets pdev_id and
param_type_id, then finally sends these data and
WMI_PDEV_SET_BIOS_INTERFACE_CMDID to firmware to set band edge channel
power.

Currently, ath12k does not have the ability to adjust Clear Channel Assessment
(CCA) threshold values to meet the regulatory requirements. Get the values from
ACPI and send them to the firmware using ath12k_wmi_set_bios_cmd() function.

In order to enable ACPI SAR (Specific Absorption Rate), ath12k gets SAR and GEO
offset tables from ACPI and sends the data to firmware using
WMI_PDEV_SET_BIOS_SAR_TABLE_CMDID and WMI_PDEV_SET_BIOS_GEO_TABLE_CMDID
commands.

Currently, ath12k does not support Time-Average-SAR (TAS). In order to enable
TAS read the tables from ACPI and send them to the firmware using
WMI_PDEV_SET_BIOS_INTERFACE_CMDID command. Besides, ath12k registers an ACPI
event callback so that ACPI can notify ath12k to get the updated SAR power
table and sends it to the firmware when the device state is changed.
ACPI is only enabled for WCN7850 using struct ath12k_hw_params::acpi_guid
field. Most likely QCN9274 will never support ACPI as the chip is not used in
laptops.
