python: rename qemu.aqmp to qemu.qmp
Now that we are fully switched over to the new QMP library, move it back
over the old namespace. This is being done primarily so that we may
upload this package simply as "qemu.qmp" without introducing confusion
over whether or not "aqmp" is a new protocol or not.
The trade-off is increased confusion inside the QEMU developer
tree. Sorry!
Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp";
not out of necessity, but just to remove any traces of the "aqmp"
name.

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.
