Introduce 'PnvChipClass::spapr_logical_pvr' to know corresponding logical
PVR of a PowerPC CPU.
This helps to have a one-to-one mapping between PVR and logical PVR for
a CPU, and used in a later commit to handle cases where PCR of two
generations of Power chip is same, which causes regressions with
compat-mode.

POWER8 does not have the ISA IRQ -> SERIRQ routing system of later
CPUs, instead all ISA IRQs are sent to the CPU via a single PSI
interrupt. There is a sanity check in the POWER8 case to ensure the
routing bits have not been set, because that would indicate a
programming error.
Those bits were incorrectly specified because of ppc bit numbering
fun. Coverity detected this as an always-zero expression.

The serirq routing table is split over two registers, the calculation
for the high irqs in the second register did not subtract the irq
offset. This was spotted by Coverity as a shift-by-negative. Fix this
and change the open-coded shifting and masking to use extract32()
function so it's less error-prone.
This went unnoticed because irqs >= 14 are not used in a standard
QEMU/OPAL boot, changing the first QEMU serial-isa irq to 14 to test
does demonstrate serial irqs aren't received, and that this change
fixes that.

divdu (without a dot) sometimes updates cr0, even though it shouldn't.
The reason is that gen_op_arith_divd() checks Rc(ctx->opcode), which is
not initialized. This field is initialized only for instructions that
go through decode_legacy(), and not decodetree.
There already was a similar issue fixed in commit 86e6202a57
("target/ppc: Make divw[u] handler method decodetree compatible.").
It's not immediately clear what else may access the uninitialized
ctx->opcode, so instead of playing whack-a-mole and changing the check
to compute_rc0, simply initialize ctx->opcode.
