ATS1HR and ATS1HW (which allow AArch32 EL2 to do address translations on the EL2 translation regime) were implemented in commit 14db7fe09a2c8. However, we got them wrong: these should do stage 1 address translations as defined for NS-EL2, which is ARMMMUIdx_S1E2. We were incorrectly making them perform stage 2 translations. A few years later in commit 1313e2d7e2cd we forgot entirely that we'd implemented ATS1Hx, and added a comment that ATS1Hx were "not supported yet". Remove the comment; there is no extra code needed to handle these operations in do_ats_write(), because arm_s1_regime_using_lpae_format() returns true for ARMMMUIdx_S1E2, which forces 64-bit PAR format.
