Add QCA vendor attributes to configure antenna selection

Add following attributes to configure antenna selection:
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_PROBE_COUNT_WLAN
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_PROBE_COUNT_BT
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_PROBE_WLAN_RSSI_THRESHOLD
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_PROBE_BT_RSSI_THRESHOLD
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_SWITCH_WLAN_RSSI_DIFF
  QCA_WLAN_VENDOR_ATTR_CONFIG_ANT_DIV_SWITCH_BT_RSSI_DIFF

If WLAN or BT RSSI is lower than the threshold, the firmware will start
a probe and then get RSSI of other antenna, and then select a better
antenna if RSSI difference is larger than the setting.
