Ricardo Maurizio Paul 36149b775e Documentation/stm32h5: document the ICACHE and the MPU.
Add an ICACHE section to the STM32H5 platform page.  With
CONFIG_STM32_ICACHE the OTP, read-only and EDATA flash areas are mapped
non-cacheable with an MPU region, so they can be read like any other
memory.

The MPU is not applied in the HardFault and NMI handlers (HFNMIENA=0),
so these areas must not be read from NMI or HardFault context: with the
ICACHE enabled such a read raises a bus fault.
