[PATCH 21/23] tcg/tci: Remove dead code for TCG_TARGET_HAS_div2_*


From: Richard Henderson
Subject: [PATCH 21/23] tcg/tci: Remove dead code for TCG_TARGET_HAS_div2_*
Date: Wed, 27 Jan 2021 22:23:29 -1000

We do not simultaneously support div and div2 -- it's one
or the other.  TCI is already using div, so remove div2.
