arm64: Allow 48-bits VA space without ARM_SMMU

Now when KVM has been reworked to support 48-bits host VA space, we can
allow systems to be configured with this option. However, the ARM SMMU
driver also needs to be tweaked for 48-bit support so only allow the
config option to be set when not including support for theSMMU.
