TLV based firmware ex. QCA6174, WCN3990 expects key cipher value
set to 9 while non-TLV firmware expects key cipher value set to 8
for enabling GCMP and GCMP-256 cipher suites.
To fix this problem, attach the key cipher suite values based on
wmi version.
Tested HW: WCN3990
Tested FW: WLAN.HL.2.0-01188-QCAHLSWMTPLZ-1
