Fix the MPU (was a no-op stub), add peripheral devices, wire them
into the tc27x SoC, and add the tc39xb SoC with TC397B machine.

The peripheral device models originate from the EFS-OpenSource
QEMU fork [1], targeting QEMU 9.x.  This series ports them to
the current QEMU 11.x baseline with API fixes and adds TC3x
register support needed for Zephyr RTOS boot.

[1] https://github.com/EFS-OpenSource/qemu-tricore-patches

Changes from the EFS baseline:
- Ported to QEMU 11 APIs (resettable phases, const class_init,
  CharFrontend, hw/core/sysbus.h, DEVICE_LITTLE_ENDIAN, etc.)
- STM: fixed address from 0xF0000000 to 0xF0001000
- IR: fixed address from 0xF0038000 to 0xF0037000
- SCU: added PLL locked status for Zephyr clock driver
- STM: switched to monotonic counter for deterministic timing

Patches 1-3: Fix memory protection registers, implement MPU,
add tc39x CPU model.

Patches 4-7: Add IR, ASCLIN UART, STM timer, SCU devices.

Patch 8: Wire peripherals into tc27x SoC.

Patch 9: Update MAINTAINERS (Orphan -> Maintained).

Patch 10: Add tc39xb SoC and KIT_AURIX_TC397_TRB machine.

Interrupt delivery and TC1.8 ISA will follow in separate series.

Single-core emulation only (CPU0).  Tested with bare-metal
firmware on TC277 and TC397B boards.  Existing TCG tests pass.

The downstream release with TC4x and interrupt support is
maintained at [2].
