wifi: ath11k: Configure the FTM responder role using firmware capability flag

Fine Time Measurement(FTM) is offloaded feature to firmware.
Hence, the configuration of FTM responder role is done using
firmware capability flag instead of hw param.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
