[zircon][utest] Do not check for the bottom 3 bits of DBGWVR The core-address-tagging test fails on bringup.arm64-[thin]lto builders in release mode. This is because an assert fails that checks the bottom 3 bits of the DBGWVR that we assign. The initial reasoning for this was because the bottom bits of DBGWVR are reserved according to the spec. This is slightly incorrect though. First is it's actually the bottom 2 bits that are reserved, not 3. Second, these bottom 2 reserved bits are alsi ignored according to the spec. From `D2.10.4 Watchpoint data address comparisons`: ``` DBGWVR<n>_EL1[1:0] are RES0 and are ignored. ``` Fixed: 103228 Change-Id: I0ca9be74f9d96ba01aea7b4770c0a59ded69d29a Reviewed-on: https://fuchsia-review.googlesource.com/c/fuchsia/+/693834 Reviewed-by: Roland McGrath <firstname.lastname@example.org> Commit-Queue: Leonard Chan <email@example.com>
