Add a model of the MPS2 FPGA image described in Application Note
AN521. This is identical to the AN505 image, except that it uses
the SSE-200 rather than the IoTKit and so has two Cortex-M33 CPUs.

In preparation for adding support for the AN521 MPS2 image, we need
to handle wiring up the MPS2 device interrupt lines to both CPUs in
the SSE-200, rather than just the one that the IoTKit has.
Abstract out a "connect to the IoTKit interrupt line" function
and make it connect to a splitter which feeds both sets of inputs
for the SSE-200 case.

Rename the files that used to be iotkit.[ch] to
armsse.[ch] to reflect the fact they new cover
multiple Arm subsystems for embedded.

The Arm IoTKit was effectively the forerunner of a series of
subsystems for embedded SoCs, named the SSE-050, SSE-100 and SSE-200:
https://developer.arm.com/products/system-design/subsystems
These are generally quite similar, though later iterations have
extra devices that earlier ones do not.
We want to add a model of the SSE-200, which means refactoring the
IoTKit code into an abstract base class and subclasses (using the
same design that the bcm283x SoC and Aspeed SoC family
implementations do). As a first step, rename the IoTKit struct and
QOM macros to ARMSSE, which is what we're going to name the base
class. We temporarily retain TYPE_IOTKIT to avoid changing the
code that instantiates a TYPE_IOTKIT device here and then changing
it back again when it is re-introduced as a subclass.

Some of the config register values we were setting for the MPS2 SCC
weren't correct:
* the SCC_AID bits [23:20] specify the FPGA build target board revision,
and the SCC_CFG4 register specifies the actual board revision, so
these should have matching values. Claim to be board revision C,
consistently -- we had the revision in the wrong part of SCC_AID.
* SCC_ID bits [15:4] should be 0x505, not decimal 505

The SPI controllers in the MPS2 AN505 board are PL022s.
We have a model of the PL022, so create these devices.
We don't currently model the LCD controller that sits behind
one of the PL022s; the others are intended to control devices
that sit on the FPGA's general purpose SPI connector or
"shield" expansion connectors.

The AN505 FPGA image includes four PL081 DMA controllers, each
of which is gated by a Master Security Controller that allows
the guest to prevent a non-secure DMA controller from accessing
memory that is used by secure guest code. Create and wire
up these devices.

The ethernet controller in the AN505 MPC FPGA image is behind
the same AHB Peripheral Protection Controller that handles
the graphics and GPIOs. (In the documentation this is clear
in the block diagram but the ethernet controller was omitted
from the table listing devices connected to the PPC.)
The ethernet sits behind AHB PPCEXP0 interface 5. We had
incorrectly claimed that this was a "gpio4", but there are
only 4 GPIOs in this image.
Correct the QEMU model to match the hardware.

Remove checks on MAX_SERIAL_PORTS that were just checking whether
they were within bounds for the serial_hds[] array and falling
back to NULL if not. This isn't needed with the serial_hd()
function, which returns NULL for all indexes beyond what the
user set up.

Define a new board model for the MPS2 with an AN505 FPGA image
containing a Cortex-M33. Since the FPGA images for TrustZone
cores (AN505, and the similar AN519 for Cortex-M23) have a
significantly different layout of devices to the non-TrustZone
images, we use a new source file rather than shoehorning them
into the existing mps2.c.
