mx5: Mark lowlevel_init board-specific code
The mx5 lowlevel_init.S contains board-specific code based on the reference
design. Let's keep it since it avoids creating new lowlevel_init files and it
may be used by many boards. But add a config to make it optional in order not to
cause issues on boards not following this part of the reference design.
