stm32h573i_dk can't boot from external flash with mcuboot

[Jowllel]

Describe the bug:

I'm trying to boot my application from the external ospi nor flash on the stm32h573i_dk board. My project (MCUBOOT_EXT_Test.zip) is based of the mcuboot sample. When I place the slot0 and slot1 partition in the internal flash everything works as expected, however when I place them in the external flash the code stops, when jumping to the application image. (As shown in the log below) At this point the MCU can't be accessed through the debugger (west attach or STM32CubeProgrammer), because it's in a locked up state.

To Reproduce:

I uploaded my project files as a zip. Build them with sysbuild and flash them to an stm32h573i_dk. And edit the board file (stm32h573i_dk.dts) in the zephyr folder, so the slot0 and slot1 partitions are placed in the ospi nor flash.

MCUBOOT_EXT_Test.zip

@Jowllel it would be more helpful for people who want to help if you could provide a git branch instead of a zip file, and reproduce the issue with a Zephyr sample (for example samples/sysbuild/with_mcuboot) if possible.
FYI there is this PR mcu-tools/mcuboot#2154 that hasn't been merged yet in upstream MCUBoot.

@Jowllel, I will go with the stm32h573 disco kit in the coming days to execute from external flash

I finally found the problem : same as for the stm32H7, the stm32H5 should not disable the PLL when booting from the MCU_Boot since the xspi is clock by the PLL
