Move the decl from ptw.h to internals.h.  Provide an inline
version for user-only, just as we do for arm_stage1_mmu_idx.
Move an endif down to make the definition in helper.c be
system only.

Should we assert(mmu_idx == ARMMMUIdx_Stage1_E0)?

You mean ARMMMUIdx_EL10_0, the stage2 idx, but no, I don't think that's useful considering 
the ifdef.
