This config option causes the warning in init_default_hcalls to fire
because the TCE handlers are in the default hcall list but not
implemented.

Hi Nick,

I checked that the TCE handlers are indeed not defined unless
CONFIG_SPAPR_TCE_IOMMU=y, and so I can see how you would hit the
warning.

This seems like the right solution to me.
