Revert "[POWERPC] Fix RTAS os-term usage on kernel panic"

This reverts commit a2b51812.

It turns out that this change caused some machines to fail to come
back up when being rebooted, and generated an error in the hypervisor
error log on some machines.  The platform architecture (PAPR) is a
little unclear on exactly when the RTAS ibm,os-term function should be
called.  Until that is clarified I'm reverting this commit.
