Add QCA_WLAN_VENDOR_ATTR_WIFI_TEST_CONFIG_11BE_EMLSR_MODE
value to allow or disallow eMLSR hardware mode for 802.11be
MLO capable devices. If this attribute is set to 1, and if
the FW supports this capability too, then the STA host
advertises this capability to AP over assoc request frame.
This attribute will not have any effect on legacy devices
with no 802.11be support.
