Michael Jung 5c1c939cdc stm32u5: Architecture Support for STM32U5
Architecture support for STMicroelectronics STMU585xx MCUs.  This is
based on corresponding code for STM32L5, but has been considerably
adjusted.  Tested with a B-U585I-IOT02A board and a simple NSH
configuration, but only running NuttX in the non-secure world with
TrustedFirmware-M.
