[PATCH v2 4/8] wifi: ath12k: introduce ath12k_hw_warn()

[Kalle Valo <kvalo@kernel.org>]

From: Kalle Valo <quic_kvalo@quicinc.com>

In the following patch we need to use ath12k_warn() but don't easily have
access to struct ath12k_base (ab) but do have access to struct ath12k_hw (ah).
So add a new warning helper ath12_hw_warn() which takes the latter but the log
output is still identical but uses the struct device pointer stored to struct
ath12k_hw.

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