Heiko Stuebner 85ecfd1a12 cmd: add a panic command
Even in boot scripts it may be needed to "panic" when all options
are exhausted and the device specification specifies hanging
instead of resetting the board.

So add a new panic command that just wraps around the core panic
call in U-Boot and can take an optional message.
