[PATCH RFC v2 3/8] wifi: ath11k: handle irq enable/disable in several code path

[Kalle Valo <kvalo@kernel.org>]

From: Baochen Qiang <quic_bqiang@quicinc.com>

For non WoW suspend/resume, ath11k host powers down whole hardware
when suspend and power up it when resume, the code path it goes
through is very like the ath11k reset logic.

In order to reuse that logic, do some IRQ management work to make
it work.

Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30
