Baochen Qiang fafa6ff082 wifi: ath12k: add support to select 6 GHz regulatory type
For 6 GHz band, firmware offers 3 types of regulatory rules for AP
mode and 6 for station mode in WMI_REG_CHAN_LIST_CC_EXT_EVENTID event.
In ath12k_reg_build_regd() current code by default chooses
WMI_REG_INDOOR_AP type rules from AP mode reg list to build regdomain,
regardless of the interface mode and power type, hence is not correct.

Pass interface mode (wmi_vdev_type) and AP power type
(ieee80211_ap_reg_power) as new arguments to ath12k_reg_build_regd()
such that we can choose correct rules based on them. Currently
ath12k_reg_build_regd() is called only by ath12k_reg_chan_list_event()
when driver boots, at that time these two arguments are not determined
yet, hence by default pass WMI_VDEV_TYPE_UNSPEC and
IEEE80211_REG_UNSET_AP, this results in WMI_REG_INDOOR_AP being chosen
at last. In upcoming patches the rules would be updated when these two
arguments could be determined.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
