Preliminary add of fdcan source files.
Some checks are pending

Build Documentation / build-html (push) Waiting to run
Adding source files to the fdcan branch based on identical register set. These files should mostly just work. Removed references to FDCAN3. H5 only has 2 FDCAN interfaces. Add basic FDCAN Kconfig FDCAN Kconfig options Added various options for FDCAN mode, FDCAN bitrate, clock selection and division, and timing. Added bit timing config options (nominal and data). Added stm32h56xxx pin mappings. Fixed Data Bit Timing. Pulled in STM32H5_FDCAN_PDIV_VALUE. Added stm32_fdcan.c to Make.defs. Added DBITRATE to Kconfig Clock source changes to FDCAN Moved the setting of the clock source to the stm32h5xx_rcc.c file. Added notes to stm32_fdcan.c that STM32_FDCAN_FREQUENCY and STM32_FDCAN_PDIV should be set in board.h Change STM32H5_FDCAN_PDIV to STM32_FDCAN_PDIV Updated Kconfig to match G4 implementation. Removed stm32_fdcan_sock for now. Removed FDCAN3 from stm32_fdcan.h incomplete changes for bit timning Set NBRP and DBRP registers based on STM32H7 FDCAN socket algorithm. Added board file for initializing 1 can device. Will update later to initialize second device. Fixed ifdefs. Changed STM32 to STM32H5. Add some can testing changes. Added option to configure bit timing, with automatic bit timing set as default. Style fixes Fixed FDCAN2 and memory access issues FDCAN2 msgram offset was wrong by 1 word (4 bytes). I removed the + 4 at the end of the definition. This fixed the issues with fdcan2. Also changed ifdefs when setting ESI, FDF, and BRS bits. When CAN FD was used, this resulted in the first command after the endif (the setting of dest at line 2325) being skipped because it was included in the else block when it shouldn't have. This resulted in exceptions. Adjust ifdefs fixes this problem. Other minor fixes. Restoring board files to upstream versions. These files will be pulled in later in a separate pull request. stm32h5_fdcan_test branch created for this. Fixed Queue Mode Transmit The can driver checks the TFFL bits in the TXFQS register. In Queue mode, this always returns 0. As a result, fdcan_txempty was always returning false, which resulted in no transmissions. This code fixes that. Add stm32h5 fdcan chardriver to Make.defs
