powerpc: Fix kgdb on little endian ppc64le
I spent some time trying to use kgdb and debugged my inability to resume from kgdb_handle_breakpoint(). NIP is not incremented and that leads to a loop in the debugger. I've tested this lightly on a virtual instance with KDB enabled. After the patch, I am able to get the "go" command to work as expected.
