BUG() and BUG_ON() are generally used to test a condition that should never happen. If it does, it is a bug.
Linux always enables them, but doing so in U-Boot causes image size problems on some platforms. Introduce CONFIG_ENABLE_BUG_CHECKS to make them no-op by default. Platforms without image size constraint are free to enable this option to catch bugs easily.
Likewise, silence WARN_ON() unless this option is enabled.
