[ Upstream commit ec613a57fa1d57381f890c3166175fe68cf43f12 ]
ISA v3.1 removes transactional memory and hence it should not be present in cpu_features or cpu_user_features2. Remove CPU_FTR_TM_COMP from CPU_FTRS_POWER10. Remove PPC_FEATURE2_HTM_COMP and PPC_FEATURE2_HTM_NOSC_COMP from COMMON_USER2_POWER10.
