That isn't wrong, because for M-profile FEAT_WFxT doesn't exist and the default handling for "no cpu_exec_halt method" is correct, but it's perhaps a little confusing. We would also like to make setting the cpu_exec_halt method mandatory. Initialize arm_v7m_tcg_ops cpu_exec_halt to the same function we use for A-profile. (On M-profile we never set up the wfxt timer so there is no change in behaviour here.)
