qcacmn: Add support for FT SAE and FT Suite-B

Browse source 
Previously host driver only supports initial SAE and Suite-B
authentication types and roaming to SAE AP is blocked. The
802.11 specification has introduced the Akm suite 00:0F:AC:9 for
FT-SAE and 00:0F:AC:13 for FT Suite-B akm type. Add support for
FT-SAE and FT-Suite-B.

Extend the enum wlan_auth_type to include WLAN_AUTH_TYPE_FT_SAE,
WLAN_AUTH_TYPE_FT_SUITEB_EAP_SHA384. This enum wlan_auth_type is
the new implementation for akm type in converged scan module
corresponding to the legacy eCsrAuthType enum.

Add changes in scan module filter to support FT-SAE and
FT-Suite-B authentication suites be added to filter->auth_type.
csr_scan_get_result() will translate the legacy eCsrAuthType
to wlan_auth_type and push it to the filter->auth_type.
