This set of minor patches to the STM32CubeU5 files is necessary to support

building for the STM32U545 chip.  These changes have been provided to
ST (https://github.com/STMicroelectronics/STM32CubeU5/issues/41

).  However,
they have fixed the issue internally and are awaiting a future release to
push them out.

I am in the process of creating a PR for Zephyr-proper to add support for
the STM32U545 part as well as the Nucleo-U545RE-Q board.  That PR is
dependent on these changes.
