Currently the wmi service bis is report from firmware, it is divided
to 128 bits for each segment. The first segment is processed by
ath11k_wmi_service_bitmap_copy(), the second segment is processed by
ath11k_service_available_event() with WMI_TAG_SERVICE_AVAILABLE_EVENT,
When the service bit exceed 256 bits, then firmware report it by tag
WMI_TAG_ARRAY_UINT32 in WMI_SERVICE_AVAILABLE_EVENTID.
ath11k does not process the third segment, this is to extend the wmi
service bits from 256 to 384 for the third 128 bits. The 3 enum value
WMI_MAX_SERVICE(128)/WMI_MAX_EXT_SERVICE(256)/WMI_MAX_EXT2_SERVICE(384)
are convenient to process the service bits.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1

In order to support different power levels of 6 GHz AP and client, new
wmi event for regulatory was added in firmware(WMI_REG_CHAN_LIST_CC_EXT_EVENTID)
to provide new parameters required for 6 GHz regulatory rules.
firmware advertises its capability of handling new event in wmi service ready
event. Based on that, host needs to set host_service_flags in wmi init
command to indicate that host supports processing of new wmi event.
Based on advertised host capability, firmware decides to send old event
(WMI_REG_CHAN_LIST_CC_EVENTID) or new event(WMI_REG_CHAN_LIST_CC_EXT_EVENTID).
Add support for parsing 2.4 GHz/5 GHz/6 GHz reg rules and other parameters from
WMI_REG_CHAN_LIST_CC_EXT_EVENTID, to populate the channel lists.
Since 6 GHz requires additional power value fields(PSD info), update
reg rule parsing function.

To: ath11k; +Cc: linux-wireless, quic_wgong
There are 3 types of regulatory rules for AP mode and 6 type for
station mode. Add wmi_vdev_type and ieee80211_ap_reg_power to
select the exact reg rules.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1

Currently ath11k support both station/AP mode for WCN6855, and it is
configured with single_pdev_only, it means it has only one ath11k
and one ieee80211_hw which registered in mac80211 and one wiphy
registered in cfg80211. Now it does not have requirement to start
up both station and AP interface simultaneously for WCN6855, this
is to disable station and AP concurrency mode.
After this patch, when station interface is up, then AP interface
can not start up. AP interface can start up after station interface
down. Also when AP interface is up, station interface can not start
up. station interface can start up after AP interface down.

The regulatory info of WMI_REG_CHAN_LIST_CC_EXT_EVENTID is not saved
in ath11k now, the info should be saved in ath11k. Save the info for
each radio and support switch regulatory rules dynamically.

When wlan boot up, WMI_REG_CHAN_LIST_CC_EXT_EVENTID is sent from
firmware at an early stage, the interface mode is not decided at
this point, then ath11k select reg rules of AP mode as default.
After interface is created, it is exactly decided AP/station mode,
then ath11k need to update reg rules to the exact one.

When station connect to AP on 6 GHz band, it need switch the regulatory
rules according to the regulatory info subfield in HE operation element.
Swith to the power type of AP for station mode.

Save the max tx power received in the vdev start response event from
firmware. A subsequent patch will use this to calculate the final power
value for WMI_VDEV_SET_TPC_POWER_CMDID.

Firmware advertises support for SERVICE_EXT_TPC_REG via a WMI service bit.
Add the definition of this service bit so that a subsequent patch can
check whether or not firmware supports this service.

When station is connected to a 6 GHz AP, it has 2 way to configure
the power limit to firmware. The first way is to send 2 wmi command
WMI_PDEV_PARAM_TXPOWER_LIMIT2G/WMI_PDEV_PARAM_TXPOWER_LIMIT5G to
firmware, the second way is to send WMI_VDEV_SET_TPC_POWER_CMDID to
firmware which include more parameters for power control.
When firmware support SERVICE_EXT_TPC_REG, it means firmware support
the second way for WMI_VDEV_SET_TPC_POWER_CMDID, then ath11k discard
BSS_CHANGED_TXPOWER flag from mac80211 which is used to the first way
for 6 GHz band in this patch and select the second way in the subsequent
patch.

When station is connected to a 6 GHz AP, it has 2 way to configure
the power limit to firmware. The first way is to send 2 wmi command
WMI_PDEV_PARAM_TXPOWER_LIMIT2G/WMI_PDEV_PARAM_TXPOWER_LIMIT5G to
firmware, the second way is to send WMI_VDEV_SET_TPC_POWER_CMDID to
firmware which include more parameters for power control.
The first way is disabled in previous patch
"ath11k: discard BSS_CHANGED_TXPOWER when EXT_TPC_REG_SUPPORT for 6 GHz".
Prepare the parameter for wmi command WMI_VDEV_SET_TPC_POWER_CMDID and
send the firmware after vdev start response success from firmware, it
is for the second way of power control.
