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.

For instance the Musca-B1 board sets it to 128K (17 bits). Make the bank size a QOM property. We follow the SSE-200 hardware in naming the parameter SRAM_ADDR_WIDTH, which specifies the number of address bits of a single SRAM bank.

These see the same view of memory, with the exception of the "private CPU region" which has per-CPU devices. Internal device interrupts for SSE-200 devices are mostly wired up to both CPUs, with the exception of a few per-CPU devices. External GPIO inputs on the SSE-200 device are provided for the second CPU's interrupts above 32, as is already the case for the first CPU. Refactor the code to support creation of multiple CPUs. For the moment we leave all CPUs with the same view of memory: this will not work in the multiple-CPU case, but we will fix this in the following commit.

User mode can only handle the positive half of the address space, so that makes a limit of 48 bits. (With LVA, it would be 53 and 52 bits respectively.) The incorrectly large address space conflicts with PAuth instructions, which use bits 48-54 and 56-63 for the pointer authentication code. This also conflicts with (as yet unsupported by QEMU) data tagging and with the ARMv8.5-MTE extension.
