Subject: [PATCH 3/3] ath11k: support SMPS configuration for 6 GHz
Date:   Mon, 13 Sep 2021 20:55:10 +0300

From: Pradeep Kumar Chitrapu <pradeepc@codeaurora.org>

Parse SMPS configuration from IEs and configure. Without this,
SMPS is not enabled for 6 GHz band.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01386-QCAHKSWPL_SILICONZ-1
