wifi: ath12k: use WMI_VDEV_SET_TPC_POWER_CMDID when EXT_TPC_REG_SUPPORT for 6 GHz

Browse Source 
When station is connected to a 6 GHz AP, there are 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
includes more parameters for power control.

When firmware advertises WMI_TLV_SERVICE_EXT_TPC_REG_SUPPORT, it supports
WMI_VDEV_SET_TPC_POWER_CMDID, ath12k uses it to send more parameters to
firmware. As chanctx is needed to extract necessary info for this command,
save it beforehand in ath12k_mac_op_assign_vif_chanctx().

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
