Balbir Singh 5ee573e8ef powerpc/powernv/mce: Don't silently restart the machine 
On MCE the current code will restart the machine with
ppc_md.restart(). This case was extremely unlikely since
prior to that a skiboot call is made and that resulted in
a checkstop for analysis.

With newer skiboots, on P9 we don't checkstop the box by
default, instead we return back to the kernel to extract
useful information at the time of the MCE. While we still
get this information, this patch converts the restart to
a panic(), so that if configured a dump can be taken and
we can track and probably debug the potential issue causing
the MCE.
