This patchset adds a model of the Arm Musca devboards
('musca-a' and 'musca-b1').
These boards are described here:
https://developer.arm.com/products/system-design/development-boards/iot-test-chips-and-boards/musca-a-test-chip-board
https://developer.arm.com/products/system-design/development-boards/iot-test-chips-and-boards/musca-b-test-chip-board

They're based on the SSE-200 subsystem for embedded which
we already have a model of. The two boards are somewhat
similar but have a different layout of devices (Musca-B1
puts them behind a more sophisticated PPC setup).

I've tested Musca-A with the Zephyr RTOS's "hello world"
program, and Musca-B1 with Arm Trusted Firmware M.
(Arm-TFM does in theory support also Musca-A, but in practice
it requires proper QSPI flash device support there; Zephyr
currently supports only Musca-A.)

Zephyr getting started guide:
https://docs.zephyrproject.org/latest/getting_started/index.html
Arm-TFM build instructions:
https://git.trustedfirmware.org/trusted-firmware-m.git/about/docs/user_guides/tfm_build_instruction.md

The first half of the patchset is some fairly straightforward
bugfixes and enhancements to various devices; the second half
does the actual implementation.
