Subject: [PATCH 3/8] wifi: ath12k: Add ath12k_get_num_hw api

From: Karthikeyan Periyasamy <quic_periyasa@quicinc.com>

Currently, one or more ath12k_hw is part of device (ath12k_base) but
in future, ath12k_hw would be part of device group (ath12k_hw_group).
Hence, num_hw under device would be moved to device group.

To facilitate above transition, add helper ath12k_get_num_hw() api to
get the number of radios per device. In future, this helper would be
able to get the number of radios in a device group.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
