[POWERPC] Make instruction dumping work in real mode

Browse source

On non-book-E, exceptions execute in real mode.  If a fault happens
that leads to a register dump, the kernel currently prints XXXXXXXX
because it doesn't realize that PC is a physical address.

This patch checks whether instruction address translation is turned
on, and if not converts PC into a virtual address.
