soc: fvp_aemv8r_aarch32: fix MPU region gap for nocache

Browse source 
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.
