PR #1209 -> 2024q3.

Detailed changelog

2024-09-26: Add support for STM32C0

PR #1188 -> a7cfe65.
Tested in hardware by @Apehaenger and @salkinium.

2024-09-25: Add FDCAN driver for STM32H7

Queue Mode will send CAN frames in priority order according to their
arbitration ID. This is inconsistent with modm's software-managed queue
which is a strict FIFO. To make the behavior of the driver consistent
with an end-to-end FIFO order, we disable Queue Mode by default.

There is a new lbuild option, tx_hw_queue_mode, which allows the user
to opt back into the old behavior if desired. This is mostly intended
for if they also set buffer.tx to zero and optionally increase
message_ram.tx_fifo_elements.

using UartN = BufferedUart<U(s)artHalN>;
// using only TX software buffer
using UartN = BufferedUart<U(s)artHalN, UartTxBuffer<512>>;
// using only RX software buffer
using UartN = BufferedUart<U(s)artHalN, UartRxBuffer<256>>;

2024q1 release

This release covers everything from 2024-01-01 and has been tested with avr-gcc
v12.2.0 from Upstream and arm-none-eabi-gcc v12.2.1 from xpack.

Breaking changes:

• TinyUSB v0.16 implements a DFU class in addition to a DFU runtime class.
  Therefore the modm:tinyusb:config:device.dfu option was renamed to
  device.dfu_rt to align with the TinyUSB naming.
• TinyUSB v0.16 improves support for using two USB ports at the same time. A
  differnt port can now be chosen for device and host classes. In addition, the
  HS peripheral may be operated in FS mode, therefore the modm:tinyusb:speed
  option was renamed to modm:tinyusb:max-speed since it now has a different
  meaning.

  hosted-linux. Its GPIO implementation based on wiringPi is removed.

Features:

• Add USB High-Speed support to all development boards with ULPI interface.
