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.
