include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST

Now that all of the Property arrays are counted, we can remove
the terminator object from each array. Update the assertions
in device_class_set_props to match.

With struct Property being 88 bytes, this was a rather large
form of terminator. Saves 30k from qemu-system-aarch64.

ppc/pnv: Move timebase state into PnvCore

The timebase state machine is per per-core state and can be driven
by any thread in the core. It is currently implemented as a hack
where the state is in a CPU structure and only thread 0's state is
accessed by the chiptod, which limits programming the timebase
side of the state machine to thread 0 of a core.

Move the state out into PnvCore and share it among all threads.

ppc/pnv: Implement the ChipTOD to Core transfer

One of the functions of the ChipTOD is to transfer TOD to the Core
(aka PC - Pervasive Core) timebase facility.

The ChipTOD can be programmed with a target address to send the TOD
value to. The hardware implementation seems to perform this by
sending the TOD value to a SCOM address.

This implementation grabs the core directly and manipulates the
timebase facility state in the core. This is a hack, but it works
enough for now. A better implementation would implement the transfer
to the PnvCore xscom register and drive the timebase state machine
from there.

ppc/pnv: Add POWER9/10 chiptod model

The ChipTOD (for Time-Of-Day) is a chip pervasive facility in IBM POWER
(powernv) processors that keeps a time of day clock.

In particular for this model are facilities that initialise and start
the time of day clock, and that synchronise that clock to cores on the
chip, and to other chips. In this way, all cores on all chips can
synchronise timebase (TB).

This model implements functionality sufficient to run the skiboot
chiptod synchronisation procedure (with the following core timebase
state machine implementation). It does not modify the TB in the cores
where the real hardware would, because the QEMU ppc timebase
implementation is always synchronised acros all cores.
