target/ppc: Add two missing register callbacks on POWER10
This patch adds tcg accessors for 2 SPRs which were missing on P10:
- the TBU40 register is used to write the upper 40 bits of the
timebase register. It is used by kvm to update the timebase when
entering/exiting the guest on P9 and above. The missing definition was
causing erratic decrementer interrupts in a pseries/kvm guest running
in a powernv10/tcg host, typically resulting in hangs.
- the missing DPDES SPR was found through code inspection. It exists
unchanged on P10.
Both existed on previous versions of the processor and a bit of git
archaeology hints that they were added while the P10 model was already
being worked on so they may have simply fallen through the cracks.
The phb3/phb4/phb5 root ports inherit from the default PCIE root port
implementation, which requests a LSI interrupt (#INTA). On real
hardware (POWER8/POWER9/POWER10), there is no such LSI. This patch
corrects it so that it matches the hardware.
As a consequence, the device tree previously generated was bogus, as
the root bridge LSI was not properly mapped. On some
implementation (powernv9), it was leading to inconsistent interrupt
controller (xive) data. With this patch, it is now clean.

This patch skips [de]asserting a LSI interrupt if the device doesn't
have any LSI defined. Doing so would trigger an assert in
pci_irq_handler().
The PCIE root port implementation in qemu requests a LSI (INTA), but a
subclass may want to change that behavior since it's a valid
configuration. For example on the POWER8/POWER9/POWER10 systems, the
root bridge doesn't request any LSI.

On HW, the PSI and FSP interrupt levels are muxed under the same
interrupt number. For coding reasons, an extra IRQ number was
introduced to index register values in an array. It increased the
count of IRQs which do not fit in the PSI IRQ range anymore.
The PSI and FSP interrupts should be modeled with an extra level of
GPIO lines but since QEMU does not support them, simply drop the extra
number to stay within the IRQ range.

globals across extended basic blocks. This means that
the liveness computed in pass 1 does not kill globals
in the same way as normal temps.
Introduce TYPE_EBB to match this lifetime, so that we
get correct register allocation for the temps that we
introduce during the indirect lowering pass.

replace it with a custom 5.16.12 kernel with all the architecture

the kernel which has a few tools for stress testing the memory
subsystem. The userspace also targets the Neoverse N1 processor so
would fail with a v8.0 cpu like cortex-a53.
