From: Carl Huang <cjhuang at codeaurora.org>
BugLink: https://bugs.launchpad.net/bugs/1879633
Host needs to use wmi command WMI_PDEV_SET_HW_MODE_CMDID to put hardware to dbs
mode instead of wmi_init command. This fixes a few strange stability issues.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
