Series irqchip/stm32-exti: split MCU and MPU code, allow module build | expand

Commit Message

Antonio Borneo May 6, 2024, 1:32 p.m. UTC 
Allow build the driver as a module by adding the necessarily hooks
in Kconfig and in the driver's code.

Since all the probe dependencies linked to this driver has already
been fixed, ignore the no more relevant 'arch_initcall'.
