[v9,00/12] wifi: ath11k: add support for 6 GHz station for various modes : LPI, SP and VLP

This introduced some new concept:
power type of AP(STANDARD_POWER_AP, INDOOR_AP, VERY_LOW_POWER_AP)
power type of STATION(DEFAULT_CLIENT, SUBORDINATE_CLIENT)
power spectral density(psd)

This patchset is to implement the new rules for 6 GHz band in
ath11k.

ath11k parsed the reg rules from new WMI event
WMI_REG_CHAN_LIST_CC_EXT_EVENTID and parse the
transmit power envelope element in beacon of AP
and then set new WMI command WMI_VDEV_SET_TPC_POWER_CMDID
to firmware when connect to 6G AP, also support backward
compatibility with firmware which not support new wmi
cmd WMI_VDEV_SET_TPC_POWER_CMDID.

v9；
 1. [PATCH 02/12] wifi: ath11k: store cur_regulatory_info for each radio:
  a. add check to soc->reg_info_store in case memory allocation fails.
  b. remove irrelevant change w.r.t commit message.

 2. [PATCH 04/12] wifi: ath11k: update regulatory rules when interface added:
  a. remove unnecessary parenthesis.
  b. remove irrelevant change w.r.t commit message.

 3. [PATCH 12/12] wifi: ath11k: discard BSS_CHANGED_TXPOWER when EXT_TPC_REG_SUPPORT for 6 GHz
drop below patch:
  a. do not discard txpower setting for BSS_CHANGED_TXPOWER.
  b. renamed subject as below and update commit log:
  	wifi: ath11k: use WMI_VDEV_SET_TPC_POWER_CMDID when
    		EXT_TPC_REG_SUPPORT for 6 GHz

 4. rebased to ToT.

v8:
    add my own s-o-b tag to each patch if not present. Also rebased to ToT.

v7: address review comments per Kalle, Jeff and Aditya. Also rebased to ToT.

v6: (NOT depends to any patch now)
   1. The dependent patch "wifi: cfg80211: save power spectral density(psd) of regulatory rule"
      has upstream to wireless-next https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/commit/?id=ddd7f45c899f7524bdbe6a32fe4906cde8b07b9b
      The prerequisite-patch is cherry-pick from wireless-next
      So add back the other patches in v3 since no dependency to cfg80211 public patch above now.
