This series adds the ZynqMP Power Management Unit (PMU) machine with basic
functionality.

The machine only has the
 - CPU
 - Memory
 - Interrupt controller
 - IPI device

connected, but that is enough to run some of the ROM and firmware
code on the machine

The series also adds the IPI device and connects it to the ZynqMP ARM
side and the ZynqMP PMU. These IPI devices don't connect between the ARM
and MicroBlaze instances though.

V4:
 - Rename the ZCU102 machine to just ZynqMP
 - Rename the PMC SoC to "xlnx,zynqmp-pmu-soc"
 - Move the IPI device to the machine instead of the SoC
V3:
 - Add the interrupt controller
 - Replace some of the error_fatals with errp
 - Fix the PMU CPU name

The Xilinx ZynqMP SoC has two main processing systems in it. The ARM
processing system (which is already modeled in QEMU) and the MicroBlaze
Power Management Unit (PMU). This is the inital work for adding support
for the PMU.

The PMU susbsystem runs along side the ARM system on hardware, but due
to architecture limitations in QEMU the two instances are seperate for
the time being.

Let's follow the same setup we do with the ARM system, where there is an
SoC device and a ZCU102 board. Although the PMU is less board specific
we are still going to follow the same split as maybe in future we can
connect the PMU device to the ARM ZCU102 board. As the machine will be
fairly small let's keep them both together in one file.

V4:
 - Rename to remove ZCU102 name

In preperation for having an ARM and MicroBlaze ZynqMP machine let's
split out the current ARM specific config options.
