Similar to commit (d736b6eb451b, "xen/arm: mpu: Define Xen start address for MPU systems"), one needs to add a build assertion to ensure that the page size is 4KB on arm32 based systems as well. The existing build assertion is moved under "xen/arch/arm/mpu" as it applies for both arm64 and arm32 based systems.
