Adds an FDCAN driver for STM32H7 MCUs using the SocketCAN interface
Note that pinmap.h, irq.h, fdcan.h still need to be updated with proper register definitions for the FDCAN3 peripheral present in STM32H7[2|3][3|5] MCUs

@JacobCrabill thanks for this! I assume I can use this backport to talk to a CAN (not CAN-FD) device on an STM32H7, right? And do you happen to have any example around where this is used, or how it would be used? |

Summary
Backport of apache/nuttx#6057
Adds SocketCAN driver for STM32H7 MCUs.
Impact
Enables SocketCAN usage on all STM32H7 boards which have a CAN interface available (needed for UAVCANv1 / Cyphal within PX4).
Testing
So far, only a version based on top of NuttX 10.3.0[+] has been tested on hardware - I plan to repeat my basic integration tests using this branch soon.
(These tests will involve building PX4 for several H7 boards and testing UAVCANv1 / Cyphal support with both CAN2.0B and CAN-FD frames).
Future TODOs
