soc: fvp_aemv8r_aarch32: fix MPU region gap for nocache

When CONFIG_NOCACHE_MEMORY=y, the .nocache section is placed in between __rodata_region_end and _app_smem_start/__kernel_ram_start. Make sure this region is covered by the MPU background region so that the static region for nocache is configured correctly. Signed-off-by: Manuel Argüelles <[email protected]>
