wifi: ath12k: Send WMI_VDEV_SET_TPC_POWER_CMD for AP vdev

Browse Source 
The power value is 6 dBm on an AP operating on the 6 GHz channel.
This is a very low value.

On 6 GHz, the target computes the EIRP based on the power values sent
in the WMI_VDEV_SET_TPC_POWER_CMD. Currently, this is being sent only
for station interfaces and not for AP interfaces.

Therefore, add AP vdev to the condition in
ath12k_mac_station_supports_tpc() and rename
ath12k_mac_station_supports_tpc() to ath12k_mac_supports_tpc().

For a AP vdev, hardcode ap_power_type as IEEE80211_REG_LPI_AP, which is
filled in the WMI_VDEV_SET_TPC_POWER_CMDID sent to the target.
Currently, LPI is the only supported AP power mode. Since there is
no method currently to set the AP power mode from user-space, the
power mode is hard-coded to LPI.

Retain the existing logic for populating the power mode for a station
vdev.
