From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
LEAutoSecurity can be used to enable/disable automatic upgrades of
security for LE devices, by default it is enabled so existing devices
that did not require security and were not bonded will automatically
upgrade the security.
Note: Platforms disabling this setting would require users to manually
bond the device which may require changes to the user interface to
always force bonding for input devices as APIs such as Device.Connect
will no longer work which maybe perceived as a regression.
