spapr: Force 32bit when resetting a core
"PowerPC Processor binding to IEEE 1275" says in
"8.2.1. Initial Register Values" that the initial state is defined as
32bit so do it for both SLOF and VOF.
This should not cause behavioral change as SLOF switches to 64bit very
early anyway. As nothing enforces LE anywhere, this drops it for VOF.
The goal is to make VOF work with TCG as otherwise it barfs with
qemu: fatal: TCG hflags mismatch (current:0x6c000004 rebuilt:0x6c000000)
