Sparc and PPC use -prom-env 'auto-boot?=false' for !BIOSPROMPT
equivalent: OpenBIOS boots without delay from the device specified
with -boot, with auto-boot? variable set to false you get the Forth
prompt.

It would be possible to add FW_CFG_BIOSPROMPT support to OpenBIOS, but
it's duplicate functionality.
