Subject: [PATCH ath-next 00/15] wifi: ath12k: add support for 6 GHz station
 for various modes : LPI, SP and VLP

Currently for 6 GHz reg rules from WMI_REG_CHAN_LIST_CC_EXT_EVENTID event,
host chooses low power indoor type rule regardless of interface type or AP's
power type, which is not correct. This series change to choose proper rule
based on interface type and AP's power type.

When connecting to a 6 GHz AP, currently host sends power settings to firmware
over WMI_PDEV_PARAM_TXPOWER_LIMIT2G/WMI_PDEV_PARAM_TXPOWER_LIMIT5G commands.
Actually there is a new command WMI_VDEV_SET_TPC_POWER_CMDID with which host
can send more detailed parameter than with those two. So add support for this
interface.

Before above changes, some fix and refactor are done to do some preparation
for following patches.
