At early U-Boot stage, before relocation, MMU is not yet configured and disabled. DDR may not be configured with the correct memory attributes (can be configured in MT_DEVICE instead of MT_MEMORY).
In this case, usage of memcpy_{from, to}io() may leads to synchronous abort in AARCH64 in case the normal memory address is not 64Bits aligned.
To avoid such situation, forbid usage of normal memory cast to (u64 *) in case MMU is not enabled.

Applied to u-boot/master, thanks!
