From: Richard Henderson <richard.henderson@linaro.org>

We already have the full ARMMMUIdx as computed from the
function parameter.

For the purpose of regime_has_2_ranges, we can ignore any
difference between AccType_Normal and AccType_Unpriv, which
would be the only difference between the passed mmu_idx
and arm_mmu_idx_el.
