MISRA: Unmark Rules 1.1 and 2.1 as clean following Eclair upgrade

Updating the Eclair runner has had knock-on effects with previously-clean
rules now flagging violations:

 - x86:   Rule 1.1, 1940 violations
 - ARM64: Rule 1.1, 725 violations, Rule 2.1, 255 violations

Fixes: 631f535a3d ("xen: update ECLAIR service identifiers from MC3R1 to MC3A2.")

(cherry picked from commit 171cb318de)
[Xen 4.18 doesn't have R2.1 as clean.  However, D4.11 is unclean too]
