This tries to faithfully reproduce the odd BookE logic. Note the e206 check in gen_msync_4xx() is always false, so not carried over. It does change the handling of non-zero reserved bits outside the defined fields from being illegal to being ignored, which the architecture specifies ot help with backward compatibility of new fields. The existing behaviour causes illegal instruction exceptions when using new POWER10 sync variants that add new fields, after this the instructions are accepted and are implemented as supersets of the new behaviour, as intended.
