[ Upstream commit 74bb84e5117146fa73eb9d01305975c53022b3c3 ]
The "os-term" RTAS calls has one argument with a message address of OS termination cause. rtas_os_term() already passes it but the recently added prom_init's version of that missed it; it also does not fill args correctly.
This passes the message address and initializes the number of arguments.
