[PATCH 15/15] ath11k: send TPC power to firmware for 6 GHz station

[Wen Gong]

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.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
