wifi: ath11k: use WMI_VDEV_SET_TPC_POWER_CMDID when EXT_TPC_REG_SUPPORT for 6 GHz
When station is connected to a 6 GHz AP, it has 2 ways to configure
the power limit to firmware. The first way is to send 2 WMI commands
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 supports SERVICE_EXT_TPC_REG, it means firmware supports
WMI_VDEV_SET_TPC_POWER_CMDID, then ath11k selects the second way.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.23
