target/arm: Remove redundant mmu_idx lookup
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.
